UUENCODE(1C)            GENIX Programmer's Manual            UUENCODE(1C)



      NAME
           uuencode,uudecode - encode/decode a binary file for tranmission  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(1) 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  fil-
           tered  through  the  uudecode program.  This way the file is created
           automatically without human intervention.  This is possible  on  the
           uucp  network  by  either  using delivermail 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  informa-
           tion) 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.
