uuencode, uudecode - encode a binary file, or decode its representation
[-m] [ file ] name
[-o outfile] [ file ]...
are used to transmit binary files over transmission mediums
that do not support other than simple
(or by default the standard input) and writes an encoded version
to the standard output.
The encoding uses only printing
characters and includes the
mode of the file and the operand
for use by
the result will be written to standard output. By default the standard
UU encoding format will be used. If the option
is given on the command line
encoding is used instead.
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.
(or by default, the standard input) into the original form.
The resulting file is named

and will have the mode of the original file except that setuid
and execute bits are not retained. If
is /dev/stdout the result will be written to standard output.
ignores any leading and trailing lines. The program can automatically decide
which of the two supported encoding schemes are used.
The following example packages up a source tree, compresses it,
uuencodes it and mails it to a user on another system.
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
tar cf - src_tree | compress |
uuencode src_tree.tar.Z | mail sys1!sys2!user

This implementation is compliant with P1003.2b/D11.
If more than one file is given to
and the -o option is given or more than one
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).
