uuencode

uuencode [file] name | mail remotesys!usr

Convert a binary file to a form which can be sent to usr via mail. The encoding uses only printing ASCII characters and includes the mode and name of the file. When file is reconverted via uudecode on the remote system, output will be sent to name. (Therefore, when saving the encoded mail message to a file on the remote system, don't store it in a file called name or you'll overwrite it!) Note that uuencode can take standard input, so a single argument will be taken as the name to be given to the file when it is decoded.
