UUENCODE(1)						    BSD General Commands Manual 					       UUENCODE(1)

NAME
     uuencode, uudecode -- encode/decode a binary file

SYNOPSIS
     uuencode [-m] [-o output_file] [file] name
     uudecode [-cips] [file ...]
     uudecode [-i] -o output_file [file]

DESCRIPTION
     The uuencode and uudecode utilities are used to transmit binary files over transmission mediums that do not support other than simple ASCII
     data.

     The uuencode utility reads file (or by default the standard input) and writes an encoded version to the standard output, or output_file if
     one has been specified.  The encoding uses only printing ASCII characters and includes the mode of the file and the operand name for use by
     uudecode.

     The uudecode utility transforms uuencoded files (or by default, the standard input) into the original form.  The resulting file is named
     either name or (depending on options passed to uudecode) output_file and will have the mode of the original file except that setuid and exe-
     cute bits are not retained.  The uudecode utility ignores any leading and trailing lines.

     The following options are available for uuencode:

     -m     Use the Base64 method of encoding, rather than the traditional uuencode algorithm.

     -o output_file
	    Output to output_file instead of standard output.

     The following options are available for uuencode:

     -m     Use the Base64 method of encoding, rather than the traditional uuencode algorithm.

     -o output_file
	    Output to output_file instead of standard output.

     The following options are available for uudecode:

     -c     Decode more than one uuencode'd file from file if possible.

     -i     Do not overwrite files.

     -o output_file
	    Output to output_file instead of any pathname contained in the input data.

     -p     Decode file and write output to standard output.

     -s     Do not strip output pathname to base filename.  By default uudecode deletes any prefix ending with the last slash '/' for security
	    purpose.

EXAMPLES
     The following example packages up a source tree, compresses it, uuencodes it and mails it to a user on another system.  When uudecode is run
     on the target system, the file ``src_tree.tar.Z'' will be created which may then be uncompressed and extracted into the original tree.

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

     The following example unpack all uuencode'd files from your mailbox into your current working directory.

	   uudecode -c < $MAIL

     The following example extract a compress'ed tar archive from your mailbox

	   uudecode -o /dev/stdout < $MAIL | zcat | tar xfv -

BUGS
     Files encoded using the traditional algorithm are expanded by 35% (3 bytes become 4 plus control information).

HISTORY
     The uudecode and uuencode utilities appeared in 4.0BSD.
