.SH DESCRIPTION
|
||||
.PP
|
||||
\fIUuencode\fR is a famous program that converts an arbitrary (usually binary)
|
||||
file to an encoding using only 64 ASCII characters.
|
||||
\fIUudecode\fR converts it back to the original file.
|
||||
The \fIuue\fR and \fIuud\fR programs are the
|
||||
\s-1MINIX 3\s-1
|
||||
versions of these programs, and are compatible with the \s-2UNIX\s0 ones.
|
||||
The files produced can even be sent successfully over BITNET, which is
|
||||
notorious for mangling files.
|
||||
It is possible to have \fIuue\fR automatically split the encoded file up
|
||||
into small chunks.
|
||||
The output files then get the suffixes \fI.uaa\fR, \fI.uab\fR, etc., instead
|
||||
of \fI.uue\fR.
|
||||
When \fIuud\fR is given \fIfile.uaa\fR to decode, it automatically includes
|
||||
the subsequent pieces.
|
||||

.Sh DESCRIPTION
|
||||
.Nm
|
||||
and
|
||||
.Nm uudecode
|
||||
are used to transmit binary files over transmission mediums
|
||||
that do not support other than simple
|
||||
.Tn ASCII
|
||||
data.
|
||||
.Pp
|
||||
The following options are available:
|
||||
.Bl -tag -width ".Fl m"
|
||||
.It Fl m
|
||||
Use base64 encoding.
|
||||
For
|
||||
.Nm ,
|
||||
the historical uuencode algorithm is the default.
|
||||
For
|
||||
.Nm uudecode ,
|
||||
by default the encoding is automatically detected.
|
||||
.It Fl o Ar outputfile
|
||||
.Po Nm uudecode No only . Pc
|
||||
Send the decoded output data to
|
||||
.Ar outputfile .
|
||||
By default,
|
||||
.Nm uudecode
|
||||
uses the
|
||||
.Ar headername
|
||||
recorded in the header of the encoded data stream.
|
||||
.It Fl p
|
||||
.Po Nm uudecode No only . Pc
|
||||
Write the decoded file to standard output instead of to a file.
|
||||
.El
|
||||
.Pp
|
||||
.Nm
|
||||
reads
|
||||
.Ar inputfile
|
||||
(or by default the standard input) and writes an encoded version
|
||||
to (always) the standard output.
|
||||
The encoding uses only printing
|
||||
.Tn ASCII
|
||||
characters suitable for text-only transport media.
|
||||
The string
|
||||
.Ar headername
|
||||
is inserted into the output header as the
|
||||
.Ar outputfile
|
||||
to use at
|
||||
.Nm uudecode
|
||||
time.
|
||||
The header also includes the mode (permissions) of the file.
|
||||
.Pp
|
||||
.Nm uudecode
|
||||
transforms
|
||||
.Em uuencoded
|
||||
files (or by default, the standard input) into the original form.
|
||||
The resulting file is named
|
||||
.Ar headername
|
||||
as recorded in the encoded file,
|
||||
or as specified by the
|
||||
.Fl o
|
||||
option,
|
||||
and will have the mode of the original file except that setuid
|
||||
and execute bits are not retained.
|
||||
If the
|
||||
.Fl p
|
||||
option is specified, or if the output file name is given as
|
||||
.Pa /dev/stdout ,
|
||||
then the data will be written to the standard output
|
||||
instead of to a named file.
|
||||
.Nm uudecode
|
||||
ignores any leading and trailing lines.
|
||||
.Pp
|
||||
The encoded form of the file is expanded by 35%.
|
||||
Every 3 bytes become 4 plus control information.

||||
.Sh EXIT STATUS
|

The
|
||||

|

.Sh EXAMPLES
|
||||
The following example packages up a source tree, compresses it,
|
||||
uuencodes it and mails it to a user on another system.
|
||||
.Pp
|
||||
.Bd -literal -offset indent -compact
|
||||
tar czf \- src_tree \&| uuencode src_tree.tgz \&| mail user@example.com
|
||||
.Ed
|
||||
.Pp
|
||||
On the other system, if the user saves the mail to the file
|
||||
.Pa temp ,
|
||||
the following example creates the file
|
||||
.Pa src_tree.tgz
|
||||
and extracts it to make a copy of the original tree.
|
||||

.Sh SECURITY CONSIDERATIONS
|
||||
When using

.Nm uudecode
|

with files coming from dubious sources,
|
||||
always either explicitly pass the
|
||||
.Fl o
|
||||
option or check the header (the first line) of the encoded file for
|
||||
safety.
|
||||
Blindly using a
|
||||
.Ar headername
|
||||
from a hostile source can overwrite important files.

|

.Sh NAME
|
||||
.Nm uuencode
|
||||
.Nd format of an encoded uuencode file
|
||||
.Sh DESCRIPTION
|
||||
Files output by
|
||||
.Xr uuencode 1
|
||||
consist of a header line,
|
||||
followed by a number of body lines,
|
||||
and a trailer line.
|
||||
The
|
||||
.Xr uudecode 1
|
||||
command
|
||||
will ignore any lines preceding the header or
|
||||
following the trailer.
|
||||
Lines preceding a header must not, of course,
|
||||
look like a header.
|
||||
.Pp
|
||||
The header line starts with the word
|
||||
.Dq begin ,
|
||||
a space,
|
||||
a file mode (in octal),
|
||||
a space,
|
||||
and finally a string which names the file being encoded.
|
||||
.Pp
|
||||
The central engine of
|
||||
.Xr uuencode 1
|
||||
is a six-bit encoding function which outputs an
|
||||
.Tn ASCII
|
||||
character.
|
||||
The six bits to be encoded are treated as a small integer and added
|
||||
with the
|
||||
.Tn ASCII
|
||||
value for the space character (octal 40).
|
||||
The result is a printable
|
||||
.Tn ASCII
|
||||
character.
|
||||
In the case where all six bits to be encoded are zero,
|
||||
the
|
||||
.Tn ASCII
|
||||
backquote character \` (octal 140) is emitted instead of what
|
||||
would normally be a space.
|
||||
.Pp
|
||||
The body of an encoded file consists of one or more lines,
|
||||
each of which may be a maximum of 86 characters long (including the trailing
|
||||
newline).
|
||||
Each line represents an encoded chunk of data from the input file and begins
|
||||
with a byte count,
|
||||
followed by encoded bytes,
|
||||
followed by a newline.
|
||||
.Pp
|
||||
The byte count is a six-bit integer encoded with the above function,
|
||||
representing the number of bytes encoded in the rest of the line.
|
||||
The method used to encode the data expands its size by
|
||||
133% (described below).
|
||||
Therefore it is important to note that the byte count describes the size of
|
||||
the chunk of data before it is encoded, not afterwards.
|
||||
The six bit size of this number effectively limits the number of bytes
|
||||
that can be encoded in each line to a maximum of 63.
|
||||
While
|
||||
.Xr uuencode 1
|
||||
will not encode more than 45 bytes per line,
|
||||
.Xr uudecode 1
|
||||
will tolerate the maximum line size.
|
||||
.Pp
|
||||
The remaining characters in the line represent the data of the input
|
||||
file encoded as follows.
|
||||
Input data are broken into groups of three eight-bit bytes,
|
||||
which are then interpreted together as a 24-bit block.
|
||||
The first bit of the block is the highest order bit of the first character,
|
||||
and the last is the lowest order bit of the third character.
|
||||
This block is then broken into four six-bit integers which are encoded one by
|
||||
one starting from the first bit of the block.
|
||||
The result is a four character
|
||||
.Tn ASCII
|
||||
string for every three bytes of input data.
|
||||
.Pp
|
||||
Encoded lines of data continue in this manner until the input file is
|
||||
exhausted.
|
||||
The end of the body is signaled by an encoded line with a byte count
|
||||
of zero (the
|
||||
.Tn ASCII
|
||||
backquote character \`).
|
||||
.Pp
|
||||
Obviously, not every input file will be a multiple of three bytes in size.
|
||||
In these cases,
|
||||
.Xr uuencode 1
|
||||
will pad the remaining one or two bytes of data with garbage bytes until
|
||||
a three byte group is created.
|
||||
The byte count in a line containing
|
||||
garbage padding will reflect the actual number of bytes encoded, making
|
||||
it possible to convey how many bytes are garbage.
|
||||
.Pp
|
||||
The trailer line consists of
|
||||
.Dq end
|
||||
on a line by itself.

|

The interpretation of the

format relies on properties of the
|
||||
.Tn ASCII
|
||||
character set and may not work correctly on non-ASCII systems.
