uuencode and
uudecode are used to transmit binary files over transmission mediums that do not support other than simple ASCII data.
The following options are available:
uuencode reads
inputfile (or by default the standard input) and writes an encoded version to the standard output. The encoding uses only printing ASCII characters and includes the mode of the file and the operand
outputname for use by
uudecode.
uudecode transforms
uuencoded files (or by default, the standard input) into the original form. The resulting file is named
outputname as recorded in the encoded file, and will have the mode of the original file except that setuid and execute bits are not retained; if the
-p option is specified, the data will be written to the standard output instead.
uudecode ignores any leading and trailing lines.
