UUENCODE(1)       UNIX 5.0(1June1980)   UUENCODE(1)


     NAME
          uuencode,uudecode - encode/decode a binary file for
          transmission via mail

     SYNOPSIS
          uuencode [ source ] remotedest | mmmmaaaaiiiillll 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.  This is
          possible on the uucp network by either using sendmail or by
          making rmail be a link to Mail instead of mail. In each
          case, 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.

     BUGS
          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.
