- Uudecode and uuencode are two utility programs for converting binary
- files to text files and vice versa.
-
- The purpose of these programs is to enable binary files to be
- transmitted over computer networks that only accept text messages.
- A binary file is uuencoded at one end, transmitted, then uudecoded
- at the other end.
-
- Generally, a uuencoded file will be 30-40% larger on average than the
- original binary file. This is because binary files can contain arbitrary
- data, while a uuencoded file must be restricted to a subset of
- printable characters. Thus each byte of a binary file will on average
- require more than one byte storage in uuencoded form.
-
- Uudecode and uuencode are in use on Unix systems and elsewhere; these
- programs are compatible with those versions.
