UUENCODE(1) | General Commands Manual | UUENCODE(1) |
uuencode | [-m] [inputfile] headername |
uudecode | [-m] [-p | -o outputfile] [encoded-file ...] |
The following options are available:
uuencode reads inputfile (or by default the standard input) and writes an encoded version to (always) the standard output. The encoding uses only printing ASCII characters suitable for text-only transport media. The string headername is inserted into the output header as the outputfile to use at uudecode time. The header also includes the mode (permissions) of the file.
uudecode transforms uuencoded files (or by default, the standard input) into the original form. The resulting file is named headername as recorded in the encoded file, or as specified by the -o option, and will have the mode of the original file except that setuid and execute bits are not retained. If the -p option is specified, or if the output file name is given as /dev/stdout, then the data will be written to the standard output instead of to a named file. uudecode ignores any leading and trailing lines.
The encoded form of the file is expanded by 35%. Every 3 bytes become 4 plus control information.
tar czf - src_tree | uuencode src_tree.tgz | mail user@example.com
On the other system, if the user saves the mail to the file temp, the following example creates the file src_tree.tgz and extracts it to make a copy of the original tree.
uudecode temp tar xzf src_tree.tgz
