  uuencode, uudecode - Encodes or decodes a binary file


  uuencode [file] remotefile

  uudecode [file...]


  Interfaces documented	on this	reference page conform to industry standards
  as follows:

  uudecode:  XCU5.0

  uuencode:  XCU5.0

  Refer	to the standards(5) reference page for more information	about indus-
  try standards	and associated tags.


  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 recreates 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 recreated.
  This is possible on the uucp network by using	sendmail or by making rmail
  be a link to mailx. In each case, an alias must be created in	a master file
  to get the automatic invocation of uudecode.

  If neither of	the preceding facilities is 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 the mode
  or remote system name. The encoded file is an	ordinary text file.


   1.  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
	    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

   2.  In the following	example, the ex1.out file is decoded:
	    prompt>&gt; uudecode ex1.out

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

   3.  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

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