UUENCODE(1C)UUENCODE(1C)NAME
uuencode, uudecode - encode/decode a binary file for transmission via
mail
SYNOPSIS
uuencode [ source ] remotedest | mail sys1!sys2!..!decode
uudecode [ file ]
DESCRIPTION
Uuencode and uudecode are used to send a binary file via uucp (or
other) mail. This combination can be used over indirect mail links
even when uusend(1C) is not available.
Uuencode takes the named source file (default standard input) and
produces an encoded version on the standard output. The encoding uses
only printing ASCII characters, and includes the mode of the file and
the remotedest for recreation on the remote system.
Uudecode reads an encoded file, strips off any leading and trailing
lines added by mailers, and recreates the original file with the
specified mode and name.
The intent is that all mail to the user ``decode'' should be filtered
through the uudecode program. This way the file is created
automatically without human intervention. An alias must be created in
a master file to get the automatic invocation of uudecode.
If these facilities are not available, the file can be sent to a user
on the remote machine who can uudecode it manually.
The encode file has an ordinary text form and can be edited by any text
editor to change the mode or remote name.

The file is expanded by 35% (3 bytes become 4 plus control information)
causing it to take longer to transmit.
The user on the remote system who is invoking uudecode (often uucp)
must have write permission on the specified file.
