OpenDarwin 7.2.1 - man page for uuencode (opendarwin section 1)

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
     execute 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 pre-
	    fix 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 work-
     ing 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.
