$NetBSD: POSIX,v 1.10 1999/11/18 19:16:34 kristerw Exp $
|
||||
|
||||
This version of ed(1) is not strictly POSIX compliant, as described in
|
||||
the POSIX 1003.2 document. The following is a summary of the omissions,
|
||||
extensions and possible deviations from POSIX 1003.2.
|
||||
|
||||
OMISSIONS
|
||||
---------
|
||||
1) Locale(3) is not supported yet.
|
||||
|
||||
2) For backwards compatibility, the POSIX rule that says a range of
|
||||
addresses cannot be used where only a single address is expected has
|
||||
been relaxed.
|
||||
|
||||
3) To support the BSD `s' command (see extension [1] below),
|
||||
substitution patterns cannot be delimited by numbers or the characters
|
||||
`r', `g' and `p'. In contrast, POSIX specifies any character expect
|
||||
space or newline can used as a delimiter.
|
||||
|
||||
EXTENSIONS
|
||||
----------
|
||||
1) BSD commands have been implemented wherever they do not conflict with
|
||||
the POSIX standard. The BSD-ism's included are:
|
||||
i) `s' (i.e., s[n][rgp]*) to repeat a previous substitution,
|
||||
ii) `W' for appending text to an existing file,
|
||||
iii) `wq' for exiting after a write,
|
||||
iv) `z' for scrolling through the buffer, and
|
||||
v) BSD line addressing syntax (i.e., `^' and `%') is recognized.
|
||||
|
||||
2) If crypt(3) is available, files can be read and written using DES
|
||||
encryption. The `x' command prompts the user to enter a key used for
|
||||
encrypting/ decrypting subsequent reads and writes. If only a newline
|
||||
is entered as the key, then encryption is disabled. Otherwise, a key
|
||||
is read in the same manner as a password entry. The key remains in
|
||||
effect until encryption is disabled. For more information on the
|
||||
encryption algorithm, see the bdes(1) man page. Encryption/decryption
|
||||
should be fully compatible with SunOS des(1).
|
||||
|
||||
3) The POSIX interactive global commands `G' and `V' are extended to
|
||||
support multiple commands, including `a', `i' and `c'. The command
|
||||
format is the same as for the global commands `g' and `v', i.e., one
|
||||
command per line with each line, except for the last, ending in a
|
||||
backslash (\).
|
||||
|
||||
4) An extension to the POSIX file commands `E', `e', `r', `W' and `w' is
|
||||
that <file> arguments are processed for backslash escapes, i.e., any
|
||||
character preceded by a backslash is interpreted literally. If the
|
||||
first unescaped character of a <file> argument is a bang (!), then the
|
||||
rest of the line is interpreted as a shell command, and no escape
|
||||
processing is performed by ed.
|
||||
|
||||
5) For SunOS ed(1) compatibility, ed runs in restricted mode if invoked
|
||||
as red. This limits editing of files in the local directory only and
|
||||
prohibits shell commands.
|
||||
|
||||
DEVIATIONS
|
||||
----------
|
||||
1) Though ed is not a stream editor, it can be used to edit binary files.
|
||||
To assist in binary editing, when a file containing at least one ASCII
|
||||
NUL character is written, a newline is not appended if it did not
|
||||
already contain one upon reading. In particular, reading /dev/null
|
||||
prior to writing prevents appending a newline to a binary file.
|
||||
|
||||
For example, to create a file with ed containing a single NUL character:
|
||||
$ ed file
|
||||
a
|
||||
^@
|
||||
.
|
||||
r /dev/null
|
||||
wq
|
||||
|
||||
Similarly, to remove a newline from the end of binary `file':
|
||||
$ ed file
|
||||
r /dev/null
|
||||
wq
|
||||
|
||||
2) Since the behavior of `u' (undo) within a `g' (global) command list is
|
||||
not specified by POSIX, it follows the behavior of the SunOS ed:
|
||||
undo forces a global command list to be executed only once, rather than
|
||||
for each line matching a global pattern. In addtion, each instance of
|
||||
`u' within a global command undoes all previous commands (including
|
||||
undo's) in the command list. This seems the best way, since the
|
||||
alternatives are either too complicated to implement or too confusing
|
||||
to use.
|
||||
|
||||
The global/undo combination is useful for masking errors that
|
||||
would otherwise cause a script to fail. For instance, an ed script
|
||||
to remove any occurrences of either `censor1' or `censor2' might be
|
||||
written as:
|
||||
ed - file <<EOF
|
||||
1g/.*/u\
|
||||
,s/censor1//g\
|
||||
,s/censor2//g
|
||||
...
|
||||
|
||||
3) The `m' (move) command within a `g' command list also follows the SunOS
|
||||
ed implementation: any moved lines are removed from the global command's
|
||||
`active' list.
|
||||
|
||||
4) If ed is invoked with a name argument prefixed by a bang (!), then the
|
||||
remainder of the argument is interpreted as a shell command. To invoke
|
||||
ed on a file whose name starts with bang, prefix the name with a
|
||||
backslash.

$NetBSD: README,v 1.9 1995/03/21 09:04:33 cgd Exp $
|
||||
|
||||
ed is an 8-bit-clean, POSIX-compliant line editor. It should work with
|
||||
any regular expression package that conforms to the POSIX interface
|
||||
standard, such as GNU regex(3).
|
||||
|
||||
If reliable signals are supported (e.g., POSIX sigaction(2)), it should
|
||||
compile with little trouble. Otherwise, the macros SPL1() and SPL0()
|
||||
should be redefined to disable interrupts.
|
||||
|
||||
The following compiler directives are recognized:
|
||||
DES - to add encryption support (requires crypt(3))
|
||||
NO_REALLOC_NULL - if realloc(3) does not accept a NULL pointer
|
||||
BACKWARDS - for backwards compatibility
|
||||
NEED_INSQUE - if insque(3) is missing
|
||||
|
||||
The file `POSIX' describes extensions to and deviations from the POSIX
|
||||
standard.
|
||||
|
||||
The ./test directory contains regression tests for ed. The README
|
||||
file in that directory explains how to run these.
|
||||
|
||||
For a description of the ed algorithm, see Kernighan and Plauger's book
|
||||
"Software Tools in Pascal," Addison-Wesley, 1981.

.Sh DESCRIPTION
|
||||
.Nm
|
||||
is a line-oriented text editor.
|
||||
It is used to create, display, modify, and otherwise manipulate text files.
|
||||
If invoked with a
|
||||
.Ar file
|
||||
argument, then a copy of
|
||||
.Ar file
|
||||
is read into the editor's buffer.
|
||||
Changes are made to this copy and not directly to
|
||||
.Ar file
|
||||
itself.
|
||||
Upon quitting
|
||||
.Nm ,
|
||||
any changes not explicitly saved with a
|
||||
.Ic w
|
||||
command are lost.
|
||||
.Pp
|
||||
Editing is done in two distinct modes:
|
||||
.Em command
|
||||
and
|
||||
.Em input .
|
||||
When first invoked,
|
||||
.Nm
|
||||
is in command mode.
|
||||
In this mode, commands are read from the standard input and
|
||||
executed to manipulate the contents of the editor buffer.
|
||||
.Pp
|
||||
A typical command might look like:
|
||||
.Bd -literal -offset indent
|
||||
,s/old/new/g
|
||||
.Ed
|
||||
.Pp
|
||||
which replaces all occurrences of the string
|
||||
.Pa old
|
||||
with
|
||||
.Pa new .
|
||||
.Pp
|
||||
When an input command, such as
|
||||
.Ic a
|
||||
(append),
|
||||
.Ic i
|
||||
(insert),
|
||||
or
|
||||
.Ic c
|
||||
(change) is given,
|
||||
.Nm
|
||||
enters input mode.
|
||||
This is the primary means of adding text to a file.
|
||||
In this mode, no commands are available;
|
||||
instead, the standard input is written directly to the editor buffer.
|
||||
Lines consist of text up to and including a newline character.
|
||||
Input mode is terminated by entering a single period
|
||||
.Pq Ql \&.
|
||||
on a line.
|
||||
.Pp
|
||||
All
|
||||
.Nm
|
||||
commands operate on whole lines or ranges of lines; e.g.,
|
||||
the
|
||||
.Ic d
|
||||
command deletes lines; the
|
||||
.Ic m
|
||||
command moves lines, and so on.
|
||||
It is possible to modify only a portion of a line by means of replacement,
|
||||
as in the example above.
|
||||
However, even here, the
|
||||
.Ic s
|
||||
command is applied to whole lines at a time.
|
||||
.Pp
|
||||
In general,
|
||||
.Nm
|
||||
commands consist of zero or more line addresses, followed by a single
|
||||
character command and possibly additional parameters; i.e.,
|
||||
commands have the structure:
|
||||
.Bd -literal -offset indent
|
||||
[address [,address]]command[parameters]
|
||||
.Ed
|
||||
.Pp
|
||||
The address(es) indicate the line or range of lines to be affected by the
|
||||
command.
|
||||
If fewer addresses are given than the command accepts, then
|
||||
default addresses are supplied.
|
||||
.Pp
|
||||
The options are as follows:
|
||||
.Bl -tag -width Ds
|
||||
.It Fl
|
||||
Same as the
|
||||
.Fl s
|
||||
option (deprecated).
|
||||
.It Fl E
|
||||
Enables the use of extended regular expressions instead of the basic
|
||||
regular expressions that are normally used.
|
||||
.It Fl p Ar string
|
||||
Specifies a command prompt.
|
||||
This may be toggled on and off with the
|
||||
.Ic P
|
||||
command.
|
||||
.It Fl s
|
||||
Suppress diagnostics.
|
||||
This should be used if
|
||||
.Nm
|
||||
standard input is from a script.
|
||||
.It Fl x
|
||||
Prompt for an encryption key to be used in subsequent reads and writes
|
||||
(see the
|
||||
.Ic x
|
||||
command).
|
||||
.It Ar file
|
||||
Specifies the name of a file to read.
|
||||
If
|
||||
.Ar file
|
||||
is prefixed with a
|
||||
bang
|
||||
.Pq Ql \&! ,
|
||||
then it is interpreted as a shell command.
|
||||
In this case, what is read is the standard output of
|
||||
.Ar file
|
||||
executed via
|
||||
.Xr sh 1 .
|
||||
To read a file whose name begins with a bang, prefix the
|
||||
name with a backslash
|
||||
.Pq Ql \e .
|
||||
The default filename is set to
|
||||
.Ar file
|
||||
only if it is not prefixed with a bang.
|
||||
.El
|
||||
.Ss LINE ADDRESSING
|
||||
An address represents the number of a line in the buffer.
|
||||
.Nm
|
||||
maintains a
|
||||
.Em current address
|
||||
which is typically supplied to commands as the default address
|
||||
when none is specified.
|
||||
When a file is first read, the current address is set to the last line
|
||||
of the file.
|
||||
In general, the current address is set to the last line affected by a command.
|
||||
.Pp
|
||||
A line address is
|
||||
constructed from one of the bases in the list below, optionally followed
|
||||
by a numeric offset.
|
||||
The offset may include any combination of digits, operators (i.e.,
|
||||
.Sq + ,
|
||||
.Sq - ,
|
||||
and
|
||||
.Sq ^ ) ,
|
||||
and whitespace.
|
||||
Addresses are read from left to right, and their values are computed
|
||||
relative to the current address.
|
||||
.Pp
|
||||
One exception to the rule that addresses represent line numbers is the
|
||||
address
|
||||
.Em 0
|
||||
(zero).
|
||||
This means
|
||||
.Dq before the first line ,
|
||||
and is legal wherever it makes sense.
|
||||
.Pp
|
||||
An address range is two addresses separated either by a comma or semi-colon.
|
||||
The value of the first address in a range cannot exceed the
|
||||
value of the second.
|
||||
If only one address is given in a range,
|
||||
then the second address is set to the given address.
|
||||
If an
|
||||
.Em n Ns No -tuple
|
||||
of addresses is given where
|
||||
.Em n \*[Gt] 2 ,
|
||||
then the corresponding range is determined by the last two addresses in the
|
||||
.Em n Ns No -tuple.
|
||||
If only one address is expected, then the last address is used.
|
||||
.Pp
|
||||
Each address in a comma-delimited range is interpreted relative to the
|
||||
current address.
|
||||
In a semi-colon-delimited range, the first address is
|
||||
used to set the current address, and the second address is interpreted
|
||||
relative to the first.
|
||||
.Pp
|
||||
The following address symbols are recognized:
|
||||
.Bl -tag -width Ds
|
||||
.It Em \&.
|
||||
The current line (address) in the buffer.
|
||||
.It Em $
|
||||
The last line in the buffer.
|
||||
.It Em n
|
||||
The
|
||||
.Em n Ns No th
|
||||
line in the buffer where
|
||||
.Em n
|
||||
is a number in the range
|
||||
.Em [0,$] .
|
||||
.It Em - No or Em ^
|
||||
The previous line.
|
||||
This is equivalent to
|
||||
.Em -1
|
||||
and may be repeated with cumulative effect.
|
||||
.It Em -n No or Em ^n
|
||||
The
|
||||
.Em n Ns No th
|
||||
previous line, where
|
||||
.Em n
|
||||
is a non-negative number.
|
||||
.It Em +
|
||||
The next line.
|
||||
This is equivalent to
|
||||
.Em +1
|
||||
and may be repeated with cumulative effect.
|
||||
.It Em +n
|
||||
The
|
||||
.Em n Ns No th
|
||||
next line, where
|
||||
.Em n
|
||||
is a non-negative number.
|
||||
.It Em whitespace Em n
|
||||
.Em whitespace
|
||||
followed by a number
|
||||
.Em n
|
||||
is interpreted as
|
||||
.Sq Em +n .
|
||||
.It Em \&, No or Em %
|
||||
The first through last lines in the buffer.
|
||||
This is equivalent to the address range
|
||||
.Em 1,$ .
|
||||
.It Em \&;
|
||||
The current through last lines in the buffer.
|
||||
This is equivalent to the address range
|
||||
.Em .,$ .
|
||||
.It Em / Ns Ar re Ns Em /
|
||||
The next line containing the regular expression
|
||||
.Ar re .
|
||||
The search wraps to the beginning of the buffer and continues down to the
|
||||
current line, if necessary.
|
||||
.Em //
|
||||
repeats the last search.
|
||||
.It Em \&? Ns Ar re Ns Em \&?
|
||||
The previous line containing the regular expression
|
||||
.Ar re .
|
||||
The search wraps to the end of the buffer and continues up to the
|
||||
current line, if necessary.
|
||||
.Em ??
|
||||
repeats the last search.
|
||||
.It Em \&\' Ns Ar lc
|
||||
The line previously marked by a
|
||||
.Ic k
|
||||
(mark) command, where
|
||||
.Ar lc
|
||||
is a lower case letter.
|
||||
.El
|
||||
.Ss REGULAR EXPRESSIONS
|
||||
Regular expressions are patterns used in selecting text.
|
||||
For example, the
|
||||
.Nm
|
||||
command
|
||||
.Bd -literal -offset indent
|
||||
g/string/
|
||||
.Ed
|
||||
.Pp
|
||||
prints all lines containing
|
||||
.Em string .
|
||||
Regular expressions are also used by the
|
||||
.Ic s
|
||||
command for selecting old text to be replaced with new.
|
||||
.Pp
|
||||
In addition to specifying string literals, regular expressions can
|
||||
represent classes of strings.
|
||||
Strings thus represented are said to be matched by the
|
||||
corresponding regular expression.
|
||||
If it is possible for a regular expression to match several strings in
|
||||
a line, then the leftmost longest match is the one selected.
|
||||
.Pp
|
||||
The following symbols are used in constructing regular expressions:
|
||||
.Bl -tag -width Dsasdfsd
|
||||
.It Em c
|
||||
Any character
|
||||
.Em c
|
||||
not listed below, including
|
||||
.Sq { ,
|
||||
.Sq } ,
|
||||
.Sq \&( ,
|
||||
.Sq \&) ,
|
||||
.Sq \*[Lt] ,
|
||||
and
|
||||
.Sq \*[Gt]
|
||||
matches itself.
|
||||
.It Em \ec
|
||||
Any backslash-escaped character
|
||||
.Em c ,
|
||||
except for
|
||||
.Sq { ,
|
||||
.Sq } ,
|
||||
.Sq \&( ,
|
||||
.Sq \&) ,
|
||||
.Sq \*[Lt] ,
|
||||
and
|
||||
.Sq \*[Gt]
|
||||
matches itself.
|
||||
.It Em \&.
|
||||
Matches any single character.
|
||||
.It Em [char-class]
|
||||
Matches any single character in the character class
|
||||
.Em char-class .
|
||||
See
|
||||
.Sx CHARACTER CLASSES
|
||||
below for further information.
|
||||
.It Em [^char-class]
|
||||
Matches any single character, other than newline, not in the
|
||||
character class
|
||||
.Em char-class .
|
||||
.It Em ^
|
||||
If
|
||||
.Em ^
|
||||
is the first character of a regular expression, then it
|
||||
anchors the regular expression to the beginning of a line.
|
||||
Otherwise, it matches itself.
|
||||
.It Em $
|
||||
If
|
||||
.Em $
|
||||
is the last character of a regular expression,
|
||||
it anchors the regular expression to the end of a line.
|
||||
Otherwise, it matches itself.
|
||||
.It Em \e\*[Lt]
|
||||
Anchors the single character regular expression or subexpression
|
||||
immediately following it to the beginning of a word.
|
||||
(This may not be available.)
|
||||
.It Em \e\*[Gt]
|
||||
Anchors the single character regular expression or subexpression
|
||||
immediately following it to the end of a word.
|
||||
(This may not be available.)
|
||||
.It Em \e( Ns Ar re Ns Em \e)
|
||||
Defines a subexpression
|
||||
.Ar re .
|
||||
Subexpressions may be nested.
|
||||
A subsequent backreference of the form
|
||||
.Em \en ,
|
||||
where
|
||||
.Em n
|
||||
is a number in the range [1,9], expands to the text matched by the
|
||||
.Em n Ns No th
|
||||
subexpression.
|
||||
For example, the regular expression
|
||||
.Em \e(.*\e)\e1
|
||||
matches any string consisting of identical adjacent substrings.
|
||||
Subexpressions are ordered relative to their left delimiter.
|
||||
.It Em *
|
||||
Matches the single character regular expression or subexpression
|
||||
immediately preceding it zero or more times.
|
||||
If
|
||||
.Em *
|
||||
is the first character of a regular expression or subexpression,
|
||||
then it matches itself.
|
||||
The
|
||||
.Em *
|
||||
operator sometimes yields unexpected results.
|
||||
For example, the regular expression
|
||||
.Em b*
|
||||
matches the beginning of the string
|
||||
.Em abbb
|
||||
(as opposed to the substring
|
||||
.Em bbb ) ,
|
||||
since a null match is the only leftmost match.
|
||||
.Sm off
|
||||
.It Em \e{ No n,m Em \e}\ \e{ No n, Em \e}\ \& Em \e{ No n Em \e}
|
||||
.Sm on
|
||||
Matches the single character regular expression or subexpression
|
||||
immediately preceding it at least
|
||||
.Em n
|
||||
and at most
|
||||
.Em m
|
||||
times.
|
||||
If
|
||||
.Em m
|
||||
is omitted, then it matches at least
|
||||
.Em n
|
||||
times.
|
||||
If the comma is also omitted, then it matches exactly
|
||||
.Em n
|
||||
times.
|
||||
.El
|
||||
.Pp
|
||||
Additional regular expression operators may be defined depending on the
|
||||
particular
|
||||
.Xr regex 3
|
||||
implementation.
|
||||
.Ss CHARACTER CLASSES
|
||||
A character class specifies a set of characters. It is written within
|
||||
square brackets
|
||||
.Pq []
|
||||
and in its most basic form contains just the characters in the set.
|
||||
.Pp
|
||||
To include a
|
||||
.Sq \&]
|
||||
in a character class, it must be the first character.
|
||||
A range of characters may be specified by separating the end characters
|
||||
of the range with a
|
||||
.Sq \&- ,
|
||||
e.g.,
|
||||
.Sq a-z
|
||||
specifies the lower case characters.
|
||||
.Pp
|
||||
The following literals can also be used within character classes as
|
||||
shorthand for particular sets of characters:
|
||||
.Bl -tag -offset indent -compact -width [:blahblah:]
|
||||
.It [:alnum:]
|
||||
Alphanumeric characters.
|
||||
.It [:cntrl:]
|
||||
Control characters.
|
||||
.It [:lower:]
|
||||
Lowercase alphabetic characters.
|
||||
.It [:space:]
|
||||
Whitespace (space, tab, newline, form feed, etc.)
|
||||
.It [:alpha:]
|
||||
Alphabetic characters.
|
||||
.It [:digit:]
|
||||
Numeric characters (digits).
|
||||
.It [:print:]
|
||||
Printable characters.
|
||||
.It [:upper:]
|
||||
Uppercase alphabetic characters.
|
||||
.It [:blank:]
|
||||
Blank characters (space and tab).
|
||||
.It [:graph:]
|
||||
Graphical characters (printing nonblank characters).
|
||||
.It [:punct:]
|
||||
Punctuation characters.
|
||||
.It [:xdigit:]
|
||||
Hexadecimal digits.
|
||||
.El
|
||||
If
|
||||
.Sq \&-
|
||||
appears as the first or last character of a character class, then
|
||||
it matches itself.
|
||||
All other characters in a character class match themselves.
|
||||
.Pp
|
||||
Patterns in
|
||||
a character class
|
||||
of the form
|
||||
.Em [.col-elm.]
|
||||
or
|
||||
.Em [=col-elm=]
|
||||
where
|
||||
.Em col-elm
|
||||
is a
|
||||
.Em collating element
|
||||
are interpreted according to
|
||||
.Xr locale 5
|
||||
(not currently supported).
|
||||
See
|
||||
.Xr regex 3
|
||||
for an explanation of these constructs.
|
||||
.Ss COMMANDS
|
||||
All
|
||||
.Nm
|
||||
commands are single characters, though some require additional parameters.
|
||||
If a command's parameters extend over several lines, then
|
||||
each line except for the last must be terminated with a backslash
|
||||
.Pq Ql \e .
|
||||
.Pp
|
||||
In general, at most one command is allowed per line.
|
||||
However, most commands accept a print suffix, which is any of
|
||||
.Ic p
|
||||
(print),
|
||||
.Ic l
|
||||
(list),
|
||||
or
|
||||
.Ic n
|
||||
(enumerate), to print the last line affected by the command.
|
||||
.Pp
|
||||
An interrupt (typically ^C) has the effect of aborting the current command
|
||||
and returning the editor to command mode.
|
||||
.Pp
|
||||
.Nm
|
||||
recognizes the following commands.
|
||||
The commands are shown together with
|
||||
the default address or address range supplied if none is
|
||||
specified (in parentheses), and other possible arguments on the right.
|
||||
.Bl -tag -width Dxxs
|
||||
.It (.) Ns Ic a
|
||||
Appends text to the buffer after the addressed line.
|
||||
Text is entered in input mode.
|
||||
The current address is set to last line entered.
|
||||
.It (.,.) Ns Ic c
|
||||
Changes lines in the buffer.
|
||||
The addressed lines are deleted from the buffer,
|
||||
and text is appended in their place.
|
||||
Text is entered in input mode.
|
||||
The current address is set to last line entered.
|
||||
.It (.,.) Ns Ic d
|
||||
Deletes the addressed lines from the buffer.
|
||||
If there is a line after the deleted range, then the current address is set
|
||||
to this line.
|
||||
Otherwise the current address is set to the line before the deleted range.
|
||||
.It Ic e Ar file
|
||||
Edits
|
||||
.Ar file ,
|
||||
and sets the default filename.
|
||||
If
|
||||
.Ar file
|
||||
is not specified, then the default filename is used.
|
||||
Any lines in the buffer are deleted before the new file is read.
|
||||
The current address is set to the last line read.
|
||||
.It Ic e Ar !command
|
||||
Edits the standard output of
|
||||
.Ar command ,
|
||||
(see
|
||||
.Ic \&! Ar command
|
||||
below).
|
||||
The default filename is unchanged.
|
||||
Any lines in the buffer are deleted before the output of
|
||||
.Em command
|
||||
is read.
|
||||
The current address is set to the last line read.
|
||||
.It Ic E Ar file
|
||||
Edits
|
||||
.Ar file
|
||||
unconditionally.
|
||||
This is similar to the
|
||||
.Ic e
|
||||
command, except that unwritten changes are discarded without warning.
|
||||
The current address is set to the last line read.
|
||||
.It Ic f Ar file
|
||||
Sets the default filename to
|
||||
.Ar file .
|
||||
If
|
||||
.Ar file
|
||||
is not specified, then the default unescaped filename is printed.
|
||||
.It (1,$) Ns Ic g Ns Ar /re/command-list
|
||||
Applies
|
||||
.Ar command-list
|
||||
to each of the addressed lines matching a regular expression
|
||||
.Ar re .
|
||||
The current address is set to the line currently matched before
|
||||
.Ar command-list
|
||||
is executed.
|
||||
At the end of the
|
||||
.Ic g
|
||||
command, the current address is set to the last line affected by
|
||||
.Ar command-list .
|
||||
.Pp
|
||||
Each command in
|
||||
.Ar command-list
|
||||
must be on a separate line,
|
||||
and every line except for the last must be terminated by a backslash
|
||||
.Pq Sq \e .
|
||||
Any commands are allowed, except for
|
||||
.Ic g ,
|
||||
.Ic G ,
|
||||
.Ic v ,
|
||||
and
|
||||
.Ic V .
|
||||
A newline alone in
|
||||
.Ar command-list
|
||||
is equivalent to a
|
||||
.Ic p
|
||||
command.
|
||||
.It (1,$) Ns Ic G Ns Ar /re/
|
||||
Interactively edits the addressed lines matching a regular expression
|
||||
.Ar re .
|
||||
For each matching line, the line is printed, the current address is set,
|
||||
and the user is prompted to enter a
|
||||
.Ar command-list .
|
||||
At the end of the
|
||||
.Ic G
|
||||
command, the current address is set to the last line affected by (the last)
|
||||
.Ar command-list .
|
||||
.Pp
|
||||
The format of
|
||||
.Ar command-list
|
||||
is the same as that of the
|
||||
.Ic g
|
||||
command.
|
||||
A newline alone acts as a null command list.
|
||||
A single
|
||||
.Sq \*[Am]
|
||||
repeats the last non-null command list.
|
||||
.It Ic H
|
||||
Toggles the printing of error explanations.
|
||||
By default, explanations are not printed.
|
||||
It is recommended that
|
||||
.Nm
|
||||
scripts begin with this command to aid in debugging.
|
||||
.It Ic h
|
||||
Prints an explanation of the last error.
|
||||
.It (.) Ns Ic i
|
||||
Inserts text in the buffer before the current line.
|
||||
Text is entered in input mode.
|
||||
The current address is set to the last line entered.
|
||||
.It (.,.+1) Ns Ic j
|
||||
Joins the addressed lines.
|
||||
The addressed lines are deleted from the buffer and replaced by a single
|
||||
line containing their joined text.
|
||||
The current address is set to the resultant line.
|
||||
.It (.) Ns Ic k Ns Ar lc
|
||||
Marks a line with a lower case letter
|
||||
.Ar lc .
|
||||
The line can then be addressed as
|
||||
.Ar \&'lc
|
||||
(i.e., a single quote followed by
|
||||
.Ar lc )
|
||||
in subsequent commands.
|
||||
The mark is not cleared until the line is deleted or otherwise modified.
|
||||
.It (.,.) Ns Ic l
|
||||
Prints the addressed lines unambiguously.
|
||||
If a single line fills more than one screen (as might be the case
|
||||
when viewing a binary file, for instance), a
|
||||
.Dq --More--
|
||||
prompt is printed on the last line.
|
||||
.Nm
|
||||
waits until the RETURN key is pressed before displaying the next screen.
|
||||
The current address is set to the last line printed.
|
||||
.It (.,.) Ns Ic m Ns No (.)
|
||||
Moves lines in the buffer.
|
||||
The addressed lines are moved to after the
|
||||
right-hand destination address, which may be the address
|
||||
.Em 0
|
||||
(zero).
|
||||
The current address is set to the last line moved.
|
||||
.It (.,.) Ns Ic n
|
||||
Prints the addressed lines along with their line numbers.
|
||||
The current address is set to the last line printed.
|
||||
.It (.,.) Ns Ic p
|
||||
Prints the addressed lines.
|
||||
The current address is set to the last line printed.
|
||||
.It Ic P
|
||||
Toggles the command prompt on and off.
|
||||
Unless a prompt was specified with the command-line option
|
||||
.Fl p Ar string ,
|
||||
the command prompt is by default turned off.
|
||||
.It Ic q
|
||||
Quits
|
||||
.Nm .
|
||||
.It Ic Q
|
||||
Quits
|
||||
.Nm
|
||||
unconditionally.
|
||||
This is similar to the
|
||||
.Ic q
|
||||
command, except that unwritten changes are discarded without warning.
|
||||
.It ($) Ns Ic r Ar file
|
||||
Reads
|
||||
.Ar file
|
||||
to after the addressed line.
|
||||
If
|
||||
.Ar file
|
||||
is not specified, then the default filename is used.
|
||||
If there was no default filename prior to the command,
|
||||
then the default filename is set to
|
||||
.Ar file .
|
||||
Otherwise, the default filename is unchanged.
|
||||
The current address is set to the last line read.
|
||||
.It ($) Ns Ic r Ar !command
|
||||
Reads to after the addressed line the standard output of
|
||||
.Ar command ,
|
||||
(see the
|
||||
.Ic \&!
|
||||
command below).
|
||||
The default filename is unchanged.
|
||||
The current address is set to the last line read.
|
||||
.Sm off
|
||||
.It (.,.) Ic s Ar /re/replacement/ , \ (.,.) \
|
||||
Ic s Ar /re/replacement/ Em g , Ar \ (.,.) \
|
||||
Ic s Ar /re/replacement/ Em n
|
||||
.Sm on
|
||||
Replaces text in the addressed lines matching a regular expression
|
||||
.Ar re
|
||||
with
|
||||
.Ar replacement .
|
||||
By default, only the first match in each line is replaced.
|
||||
If the
|
||||
.Em g
|
||||
(global) suffix is given, then every match to be replaced.
|
||||
The
|
||||
.Em n
|
||||
suffix, where
|
||||
.Em n
|
||||
is a positive number, causes only the
|
||||
.Em n Ns No th
|
||||
match to be replaced.
|
||||
It is an error if no substitutions are performed on any of the addressed
|
||||
lines.
|
||||
The current address is set the last line affected.
|
||||
.Pp
|
||||
.Ar re
|
||||
and
|
||||
.Ar replacement
|
||||
may be delimited by any character other than space and newline
|
||||
(see the
|
||||
.Ic s
|
||||
command below).
|
||||
If one or two of the last delimiters is omitted, then the last line
|
||||
affected is printed as though the print suffix
|
||||
.Em p
|
||||
were specified.
|
||||
.Pp
|
||||
An unescaped
|
||||
.Ql \*[Am]
|
||||
in
|
||||
.Ar replacement
|
||||
is replaced by the currently matched text.
|
||||
The character sequence
|
||||
.Em \em ,
|
||||
where
|
||||
.Em m
|
||||
is a number in the range [1,9], is replaced by the
|
||||
.Em m Ns No th
|
||||
backreference expression of the matched text.
|
||||
If
|
||||
.Ar replacement
|
||||
consists of a single
|
||||
.Ql % ,
|
||||
then
|
||||
.Ar replacement
|
||||
from the last substitution is used.
|
||||
Newlines may be embedded in
|
||||
.Ar replacement
|
||||
if they are escaped with a backslash
|
||||
.Pq Ql \e .
|
||||
.It (.,.) Ns Ic s
|
||||
Repeats the last substitution.
|
||||
This form of the
|
||||
.Ic s
|
||||
command accepts a count suffix
|
||||
.Em n ,
|
||||
or any combination of the characters
|
||||
.Em r ,
|
||||
.Em g ,
|
||||
and
|
||||
.Em p .
|
||||
If a count suffix
|
||||
.Em n
|
||||
is given, then only the
|
||||
.Em n Ns No th
|
||||
match is replaced.
|
||||
The
|
||||
.Em r
|
||||
suffix causes
|
||||
the regular expression of the last search to be used instead of
|
||||
that of the last substitution.
|
||||
The
|
||||
.Em g
|
||||
suffix toggles the global suffix of the last substitution.
|
||||
The
|
||||
.Em p
|
||||
suffix toggles the print suffix of the last substitution.
|
||||
The current address is set to the last line affected.
|
||||
.It (.,.) Ns Ic t Ns No (.)
|
||||
Copies (i.e., transfers) the addressed lines to after the right-hand
|
||||
destination address, which may be the address
|
||||
.Em 0
|
||||
(zero).
|
||||
The current address is set to the last line copied.
|
||||
.It Ic u
|
||||
Undoes the last command and restores the current address
|
||||
to what it was before the command.
|
||||
The global commands
|
||||
.Ic g ,
|
||||
.Ic G ,
|
||||
.Ic v ,
|
||||
and
|
||||
.Ic V
|
||||
are treated as a single command by undo.
|
||||
.Ic u
|
||||
is its own inverse.
|
||||
.It (1,$) Ns Ic v Ns Ar /re/command-list
|
||||
Applies
|
||||
.Ar command-list
|
||||
to each of the addressed lines not matching a regular expression
|
||||
.Ar re .
|
||||
This is similar to the
|
||||
.Ic g
|
||||
command.
|
||||
.It (1,$) Ns Ic V Ns Ar /re/
|
||||
Interactively edits the addressed lines not matching a regular expression
|
||||
.Ar re .
|
||||
This is similar to the
|
||||
.Ic G
|
||||
command.
|
||||
.It (1,$) Ns Ic w Ar file
|
||||
Writes the addressed lines to
|
||||
.Ar file .
|
||||
Any previous contents of
|
||||
.Ar file
|
||||
are lost without warning.
|
||||
If there is no default filename, then the default filename is set to
|
||||
.Ar file ,
|
||||
otherwise it is unchanged.
|
||||
If no filename is specified, then the default filename is used.
|
||||
The current address is unchanged.
|
||||
.It (1,$) Ns Ic wq Ar file
|
||||
Writes the addressed lines to
|
||||
.Ar file ,
|
||||
and then executes a
|
||||
.Ic q
|
||||
command.
|
||||
.It (1,$) Ns Ic w Ar !command
|
||||
Writes the addressed lines to the standard input of
|
||||
.Ar command ,
|
||||
(see the
|
||||
.Ic \&!
|
||||
command below).
|
||||
The default filename and current address are unchanged.
|
||||
.It (1,$) Ns Ic W Ar file
|
||||
Appends the addressed lines to the end of
|
||||
.Ar file .
|
||||
This is similar to the
|
||||
.Ic w
|
||||
command, except that the previous contents of file are not clobbered.
|
||||
The current address is unchanged.
|
||||
.It Ic x
|
||||
Prompts for an encryption key which is used in subsequent reads and writes.
|
||||
If a newline alone is entered as the key, then encryption is turned off.
|
||||
Otherwise, echoing is disabled while a key is read.
|
||||
Encryption/decryption is done using the
|
||||
.Xr bdes 1
|
||||
algorithm.
|
||||
.It (.+1) Ns Ic z Ns Ar n
|
||||
Scrolls
|
||||
.Ar n
|
||||
lines at a time starting at addressed line.
|
||||
If
|
||||
.Ar n
|
||||
is not specified, then the current window size is used.
|
||||
The current address is set to the last line printed.
|
||||
.It ($) Ns Ic =
|
||||
Prints the line number of the addressed line.
|
||||
.It (.+1) Ns Ic newline
|
||||
Prints the addressed line, and sets the current address to that line.
|
||||
.It Ic \&! Ns Ar command
|
||||
Executes
|
||||
.Ar command
|
||||
via
|
||||
.Xr sh 1 .
|
||||
If the first character of
|
||||
.Ar command
|
||||
is
|
||||
.Ic \&! ,
|
||||
then it is replaced by text of the previous
|
||||
.Ic !command .
|
||||
.Nm
|
||||
does not process
|
||||
.Ar command
|
||||
for
|
||||
.Sq \e
|
||||
(backslash) escapes.
|
||||
However, an unescaped
|
||||
.Sq %
|
||||
is replaced by the default filename.
|
||||
When the shell returns from execution, a
|
||||
.Sq \&!
|
||||
is printed to the standard output.
|
||||
The current line is unchanged.
|
||||
.El
|
||||
.Sh LIMITATIONS
|
||||
.Nm
|
||||
processes
|
||||
.Em file
|
||||
arguments for backslash escapes, i.e., in a filename,
|
||||
any characters preceded by a backslash
|
||||
.Pq Ql \e
|
||||
are interpreted literally.
|
||||
.Pp
|
||||
If a text (non-binary) file is not terminated by a newline character,
|
||||
then
|
||||
.Nm
|
||||
appends one on reading/writing it.
|
||||
In the case of a binary file,
|
||||
.Nm
|
||||
does not append a newline on reading/writing.
|
||||
.Sh ENVIRONMENT
|
||||
.Bl -tag -width iTMPDIR
|
||||
.It Ev TMPDIR
|
||||
The location used to store temporary files.
|

.El
|
||||
.Sh FILES
|
||||
.Bl -tag -width /tmp/ed.* -compact
|

.It Pa /tmp/ed.*
|

.It Pa ed.hup
|

where
|
||||
.Nm
|
||||
attempts to write the buffer if the terminal hangs up
|
||||
.El
|
||||
.Sh DIAGNOSTICS
|
||||
When an error occurs,
|
||||
.Nm
|
||||
prints a
|
||||
.Dq \&?
|
||||
and either returns to command mode or exits if its input is from a script.
|
||||
An explanation of the last error can be printed with the
|
||||
.Ic h
|
||||
(help) command.
|
||||
.Pp
|
||||
Since the
|
||||
.Ic g
|
||||
(global) command masks any errors from failed searches and substitutions,
|
||||
it can be used to perform conditional operations in scripts; e.g.,
|
||||
.Bd -literal -offset indent
|
||||
g/old/s//new/
|
||||
.Ed
|
||||
.Pp
|
||||
replaces any occurrences of
|
||||
.Em old
|
||||
with
|
||||
.Em new .
|
||||
.Pp
|
||||
If the
|
||||
.Ic u
|
||||
(undo) command occurs in a global command list, then
|
||||
the command list is executed only once.
|
||||
.Pp
|
||||
If diagnostics are not disabled, attempting to quit
|
||||
.Nm
|
||||
or edit another file before writing a modified buffer results in an error.
|
||||
If the command is entered a second time, it succeeds,
|
||||
but any changes to the buffer are lost.

$NetBSD: README,v 1.8 1995/03/21 09:05:18 cgd Exp $
|
||||
|
||||
The files in this directory with suffixes `.t', `.d', `.r' and `.err' are
|
||||
used for testing ed. To run the tests, set the ED variable in the Makefile
|
||||
for the path name of the program to be tested (e.g., /bin/ed), and type
|
||||
`make'. The tests do not exhaustively verify POSIX compliance nor do
|
||||
they verify correct 8-bit or long line support.
|
||||
|
||||
The test file suffixes have the following meanings:
|
||||
.t Template - a list of ed commands from which an ed script is
|
||||
constructed
|
||||
.d Data - read by an ed script
|
||||
.r Result - the expected output after processing data via an ed
|
||||
script.
|
||||
.err Error - invalid ed commands that should generate an error
|
||||
|
||||
The output of the tests is written to the two files err.o and scripts.o.
|
||||
At the end of the tests, these files are grep'ed for error messages,
|
||||
which look like:
|
||||
*** The script u.ed exited abnormally ***
|
||||
or:
|
||||
*** Output u.o of script u.ed is incorrect ***
|
||||
|
||||
The POSIX requirement that an address range not be used where at most
|
||||
a single address is expected has been relaxed in this version of ed.
|
||||
Therefore, the following scripts which test for compliance with this
|
||||
POSIX rule exit abnormally:
|
||||
=-err.ed
|
||||
a1-err.ed
|
||||
i1-err.ed
|
||||
k1-err.ed
|
||||
r1-err.ed
