  uuencode, uudecode - Encodes or decodes a binary file


  uuencode [file] remotefile

  uudecode [file ...]


  The uuencode and uudecode commands are used to send a binary file via uucp
  (or other) mail.  This combination can be used over indirect mail links
  even when uusend is not available.

  The uuencode command takes the named file (default standard input) and pro-
  duces an encoded version on the standard output. The encoding uses only
  printing ASCII characters, and includes the mode of the file and the name
  for re-creation on the remote system, specified by remotefile.

  The uudecode command reads an encoded file, strips off any leading and
  trailing lines added by mailers, and re-creates the original file with the
  specified mode and name.  Filter the encode through the uudecode program.
  Filtering the file causes the original file to be automatically re-created.
  This is possible on the uucp network by either using sendmail or by making
  rmail be a link to mailx.  In each case, an alias must be created in a mas-
  ter file to get the automatic invocation of uudecode.

  If neither of the preceding facilities are available on a user's system,
  uudecode can be applied to the file manually by editing the file with any
  text editor, removing the trailing and leading lines, and changing either
  the mode or remote system name. The encoded file is an ordinary text file.


  In the following example, the ex1 file is encoded; the output is also
  redirected to the ex1.out file:

       prompt> uuencode ex1 ex1.en > ex1.out

  If the source ex1 file is as follows:

       This example shows
       the how to encode
       a file using
       and how to
       decode a file
       using uudecode.

  The encoded ex1.out file would be as follows:

       begin 644 ex1.en
       M uudecode ex1.out

  In this example, the uudecode command decodes the file and puts the output
  in ex1.en.

  To package up a source tree using tar, compress it, uuencode it, and mail
  it to a user on another system, enter:

       tar cf - src_tree | compress | uuencode src_tree.tar.Z
	       | mail sys1!sys2!user1

  (Enter the command entirely on one line, not on two lines as shown above.)

  When uudecode is run on the target system, the src_tree.tar.Z file is
  created; it may then be uncompressed and de-archived with tar.
