Uuencode and uudecode are used to transmit binary files over transmission mediums that do not support other than simple ASCII data.
Uuencode reads the standard input and writes an encoded version to the standard output. The encoding uses only printable ASCII characters and includes the mode of the file and the operand name for use by uudecode. By default the standard UU encoding format will be used. If the option -m is given on the command line, base64 encoding as of RFC1521 is used instead.
Remotefile is the name of the file, that will be created on the destination system.
