This will make a number of things easier in the future, as well as (finally!) avoiding the Id-smashing problem which has plagued developers for so long. Boy, I'm glad we're not using sup anymore. This update would have been insane otherwise.

.Sh NAME
|

.Nm uuencode ,
|
|
.Nm uudecode
|
|
.Nd encode/decode a binary file
|
|
.Sh SYNOPSIS
|
|
.Nm uuencode
|
|
.Op Ar file
|
|
.Ar name
|
|
.Nm uudecode
|
|
.Op Fl cp
|

.Op Ar file ...
|
|
.Sh DESCRIPTION
|
|
.Nm Uuencode
|
|
and
|
|
.Nm uudecode
|
|
are used to transmit binary files over transmission mediums
|
|
that do not support other than simple
|
|
.Tn ASCII
|
|
data.
|
|
.Pp
|
|
.Nm Uuencode
|
|
reads
|
|
.Ar file
|
|
(or by default the standard input) and writes an encoded version
|
|
to the standard output.
|
|
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
|
|
.Nm Uudecode
|
|
transforms
|
|
.Em uuencoded
|
|
files (or by default, the standard input) into the original form.
|
|
The resulting file is named
|
|
.Ar name
|
|
and will have the mode of the original file except that setuid
|
|
and execute bits are not retained.
|
|
.Nm Uudecode
|
|
ignores any leading and trailing lines.
|
|
.Pp
|
|
The following options are available for
|
|
.Nm uudecode :
|
|
.Bl -tag -width ident
|
|
.It Fl c
|
|
Decode more than one uuencode'd file from
|
|
.Ar file
|
|
if possible.
|
|
.It Fl p
|
|
Decode
|
|
.Ar file
|
|
and write output to standard output.
|
|
.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.
|
|
.Pp
|
|
.Bd -literal -offset indent -compact
|
|
tar cf \- src_tree \&| compress \&|
|
|
uuencode src_tree.tar.Z \&| mail sys1!sys2!user
|
|
.Ed
|
|
|
|
The following example unpack all uuencode'd
|
|
files from your mailbox into your current working directory.
|
|
.Pp
|
|
.Bd -literal -offset indent -compact
|
|
uudecode -c < $MAIL
|
|
.Ed
|
|
|
|
The following example extract a compress'ed tar
|
|
archive from your mailbox
|
|
.Pp
|
|
.Bd -literal -offset indent -compact
|
|

.Sh BUGS
|
|
The encoded form of the file is expanded by 35% (3 bytes become 4 plus
|
|
control information).
