Encode a binary file or standard input into ASCII (POSIX)
uuencode [-m] [file] name
The uuencode utility encodes a binary file as ASCII (e.g. for mailing). The encoding takes 3 bytes (24 bits) from the input file and renders them as 4 bytes in the output file.
By default, uuencode writes the encoded file to standard output. If you don't specify an input file, uuencode reads from standard input (unlike uue).
To decode the file, use uudecode.
