uuencode - encode a binary file
uudecode - decode a file created by uuencode
Syntax uuencode [-m] [ file ] name uudecode [-o outfile] [ file ]... Key file An input file to read. -m Use base64 encoding instead of UU encoding. name Output file. -o Output the decoded string to the file outfile
Uuencode and uudecode are used to transmit binary files over transmission mediums that do not support other than simple ASCII data. The encoding uses only printing ASCII characters and includes the mode of the file and the operand name for use by uudecode.
Uuencode reads file (or by default the standard input) and
writes an encoded version to the standard output.
The resulting file 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 transforms uuencoded files (or by default, the
standard input) into the original form.
Uudecode ignores any leading and trailing lines. The program can automatically decide which of the supported encoding schemes are used.
Debian/Ubuntu users can install uuencode as part of the ’sharutils’ group of Unix utilities with apt-get install sharutils
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 can then be uncompressed and extracted into the original tree.
tar cf - src_tree | compress | uuencode src_tree.tar.Z | mail sys1!sys2!user
