UUENCODE(C)                          UNIX System V



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


     Syntax
          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.

          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.

     Restrictions
          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.
