Encode a binary file into ASCII
uue [-n] input_file [-]
The uue 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, the output file is input_file.uue; if you specify a dash at the end of the command, uue writes the encoded file to standard output.
If you specify the -n option, uue writes the encoded file to input_file.uaa, input_file.uab, and so on.
To decode the file, use uud.
