.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.
|
|
||||||
The encoding takes 3 bytes (24 bits) from the input file and renders it
|
|
||||||
as 4 bytes in the output file.

|
.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
|
||||||
|
.Nm uudecode
|
||||||
|
and
|
||||||
|
.Nm
|
||||||
|
utilities exits 0 on success, and \*[Gt]0 if an error occurs.
|
||||||
|
.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.
|
||||||
|
.Pp
|
||||||

|
||||||
|
.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.

.Sh HISTORY
|
||||||
|
The
|
||||||
|
.Nm
|
||||||
|
file format appeared in
|
||||||
|
.Bx 4.0 .
|
||||||
|
.Sh BUGS
|
||||||
|
The interpretation of the
|
||||||
|
.Nm
|
||||||
|
format relies on properties of the
|
||||||
|
.Tn ASCII
|
||||||
|
character set and may not work correctly on non-ASCII systems.
