NAME

       uuencode - UU-encode/decode binary data

SYNOPSIS

       package require Tcl  8

       package require uuencode  ?1.1.4?

       ::uuencode::encode string

       ::uuencode::decode string

       ::uuencode::uuencode ?-name string? ?-mode octal? (-file filename | ?--? string)

       ::uuencode::uudecode (-file filename | ?--? string)

_________________________________________________________________

DESCRIPTION

       This package provides a Tcl-only implementation of the uuencode(1) and uudecode(1) commands. This encoding packs binary data into printable
       ASCII characters.

       ::uuencode::encode string
	      returns the uuencoded data. This will encode all the data passed in even if this is longer than the uuencode maximum line length. If
	      the number of input bytes is not a multiple of 3 then additional 0 bytes are added to pad the string.

       ::uuencode::decode string
	      Decodes  the  given  encoded data. This will return any padding characters as well and it is the callers responsibility to deal with
	      handling the actual length of the encoded data. (see uuencode).

       ::uuencode::uuencode ?-name string? ?-mode octal? (-file filename | ?--? string)

       ::uuencode::uudecode (-file filename | ?--? string)
	      UUDecode a file or block of data. A file may contain more than one embedded file so the result is a list where  each  element  is  a
	      three element list of filename, mode value and data.

OPTIONS

       -filename name
	      Cause the uuencode or uudecode commands to read their data from the named file rather that taking a string parameter.

       -name string
	      The  uuencoded  data header line contains the suggested file name to be used when unpacking the data. Use this option to change this
	      from the default of "data.dat".

       -mode octal
	      The uuencoded data header line contains a suggested permissions bit pattern expressed as an octal string. To change the  default	of
	      0644 you can set this option. For instance, 0755 would be suitable for an executable. See chmod(1).

EXAMPLES

	      % set d [uuencode::encode "Hello World!"]
	      2&5L;&\@5V]R;&0A

	      % uuencode::uudecode $d
	      Hello World!

	      % set d [uuencode::uuencode -name hello.txt "Hello World"]
	      begin 644 hello.txt
	      +2&5L;&@5V]R;&0`
	      `
	      end

	      % uuencode::uudecode $d
	      {hello.txt 644 {Hello World}}

NAME

       uuencode, uudecode - encode a binary file, or decode its representation

SYNOPSIS

       uuencode [-m] [ file ] name

       uudecode [-o outfile] [ file ]...

DESCRIPTION

       Uuencode and uudecode are used to transmit binary files over channels that support only simple ASCII data.

       Uuencode  reads	file  (or  by default the standard input) and writes an encoded version to the standard output, using only printable ASCII
       characters.  The encoded output begins with a header, for use by uudecode, which records the mode of the input file and suggests  name  for
       the decoded file that will be created.  (If name is /dev/stdout then uudecode will decode to standard output.)  The encoding has the format
       documented at uuencode(5), unless the option -m is given, when base64 encoding is used instead.

       Note: uuencode uses buffered input and assumes that it is not hand typed from a tty.  The consequence is that at a tty, you may need to hit
       Ctl-D several times to terminate input.

       Uudecode  transforms  uuencoded	files  (or standard input) into the original form.  The resulting file is named name (or outfile if the -o
       option is given) and will have the mode of the original file except that setuid and execute bits are not retained.  If outfile or  name	is
       /dev/stdout  the  result will be written to standard output.  Uudecode ignores any leading and trailing lines.  The program determines from
       the header which of the two supported encoding schemes was used.

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

STANDARDS

       This implementation is compliant with P1003.2b/D11.

BUGS

       If more than one file is given to uudecode and the -o option is given or more than one name in the encoded files are the same the result is
       probably not what is expected.

       The encoded form of the file is expanded by 37% for UU encoding and by 35% for base64 encoding (3 bytes become 4 plus control information).

REPORTING BUGS

       Report bugs to <bug-gnu-utils@gnu.org>.	Please put sharutils or uuencode in the subject line.  It helps to spot the message.

HISTORY

       The uuencode command appeared in BSD 4.0.
