UUENCODE(1) BSD General Commands Manual UUENCODE(1)NAME
uuencode, uudecode — encode/decode a binary file
uuencode [file] name
uudecode [file ...]
Uuencode and uudecode are used to transmit binary files over transmission
mediums that do not support other than simple ASCII data.
Uuencode reads file (or by default the standard input) and writes an
encoded version to the standard output. The encoding uses only printing
ASCII characters and includes the mode of the file and the operand name
for use by uudecode.
Uudecode transforms uuencoded files (or by default, the standard input)
into the original form. The resulting file is named name and will have
the mode of the original file except that setuid and execute bits are not
retained. Uudecode ignores any leading and trailing lines.
The following example packages up a source tree, compresses it, uuencodes
it and mails it to a user on another system. When uudecode is run on the
target system, the file ``src_tree.tar.Z'' will be created which may then
be uncompressed and extracted into the original tree.
tar cf - src_tree | compress |
uuencode src_tree.tar.Z | mail sys1!sys2!user

The encoded form of the file is expanded by 35% (3 bytes become 4 plus
The uuencode command appeared in 4.0BSD.
