.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
and
|
|
.Nm uudecode
|
|
utilities are used to transmit binary files over transmission mediums
|
|
that do not support other than simple
|
|
.Tn ASCII
|
|
data.
|
|
The
|
|
.Nm b64encode
|
|
utility is synonymous with
|
|
.Nm
|
|
with the
|
|
.Fl m
|
|
flag specified.
|
|
The
|
|
.Nm b64decode
|
|
utility is synonymous with
|
|
.Nm uudecode
|
|
with the
|
|
.Fl m
|
|
flag specified.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
utility reads
|
|
.Ar file
|
|
(or by default the standard input) and writes an encoded version
|
|
to the standard output, or
|
|
.Ar output_file
|
|
if one has been specified.
|
|
The encoding uses only printing
|
|
.Tn ASCII
|
|
characters and includes the
|
|
mode of the file and the operand
|
|
.Ar name
|
|
for use by
|
|
.Nm uudecode .
|
|
.Pp
|
|
The
|
|
.Nm uudecode
|
|
utility transforms
|
|
.Em uuencoded
|
|
files (or by default, the standard input) into the original form.
|
|
The resulting file is named either
|
|
.Ar name
|
|
or (depending on options passed to
|
|
.Nm uudecode )
|
|
.Ar output_file
|
|
and will have the mode of the original file except that setuid
|
|
and execute bits are not retained.
|
|
The
|
|
.Nm uudecode
|
|
utility ignores any leading and trailing lines.
|
|
.Pp
|
|
The following options are available for
|
|
.Nm :
|
|
.Bl -tag -width ident
|
|
.It Fl m
|
|
Use the Base64 method of encoding, rather than the traditional
|
|
.Nm
|
|
algorithm.
|
|
.It Fl o Ar output_file
|
|
Output to
|
|
.Ar output_file
|
|
instead of standard output.
|
|
.El
|
|
.Pp
|
|
The following options are available for
|
|
.Nm uudecode :
|
|
.Bl -tag -width ident
|
|
.It Fl c
|
|
Decode more than one uuencoded file from
|
|
.Ar file
|
|
if possible.
|
|
.It Fl i
|
|
Do not overwrite files.
|
|
.It Fl m
|
|
When used with the
|
|
.Fl r
|
|
flag, decode Base64 input instead of traditional
|
|
.Nm
|
|
input.
|
|
Without
|
|
.Fl r
|
|
it has no effect.
|
|
.It Fl o Ar output_file
|
|
Output to
|
|
.Ar output_file
|
|
instead of any pathname contained in the input data.
|
|
.It Fl p
|
|
Decode
|
|
.Ar file
|
|
and write output to standard output.
|
|
.It Fl r
|
|
Decode raw (or broken) input, which is missing the initial and
|
|
possibly the final framing lines.
|
|
The input is assumed to be in the traditional
|
|
.Nm
|
|
encoding, but if the
|
|
.Fl m
|
|
flag is used, or if the utility is invoked as
|
|
.Nm b64decode ,
|
|
then the input is assumed to be in Base64 format.
|
|
.It Fl s
|
|
Do not strip output pathname to base filename.
|
|
By default
|
|
.Nm uudecode
|
|
deletes any prefix ending with the last slash '/' for security
|
|
reasons.
|
|
.El
|
|
.Sh EXAMPLES
|
|
The following example packages up a source tree, compresses it,
|
|
uuencodes it and mails it to a user on another system.
|
|
When
|
|
.Nm uudecode
|
|
is run on the target system, the file ``src_tree.tar.Z'' will be
|
|
created which may then be uncompressed and extracted into the original
|
|
tree.
|
|

|
|
.Bd -literal -offset indent -compact
|
|
tar cf \- src_tree \&| compress \&|
|
|
uuencode src_tree.tar.Z \&| mail sys1!sys2!user
|
|
.Ed
|
|
.Pp
|
|
The following example unpacks all uuencoded
|
|
files from your mailbox into your current working directory.
|
|
.Pp
|
|
.Bd -literal -offset indent -compact
|
|
uudecode -c < $MAIL
|
|
.Ed
|
|
.Pp
|
|
The following example extracts a compressed tar
|
|
archive from your mailbox
|
|
.Pp
|
|
.Bd -literal -offset indent -compact
|
|
uudecode -o /dev/stdout < $MAIL | zcat | tar xfv -

.Sh BUGS
|
|
Files encoded using the traditional algorithm are expanded by 35% (3
|
|
bytes become 4 plus control information).
