uuencode !!!uuencode NAME SYNOPSIS DESCRIPTION EXAMPLES SEE ALSO STANDARDS BUGS HISTORY ---- !!NAME uuencode - encode a binary file uudecode - decode a file created by uuencode !!SYNOPSIS __uuencode__ [[-m] [[ file ] name __uudecode__ [[-o outfile] [[ file ]... !!DESCRIPTION ''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.'' If ''name'' is ''/dev/stdout'' the result will be written to standard output. By default the standard UU encoding format will be used. If the option ''-m'' is given on the command line __base64__ encoding is used instead. ''Uudecode'' transforms uuencoded ''files'' (or by default, the standard input) into the original form. The resulting file is named ''name'' (or ''outfile'' if the -o option is given) and will have the mode of the original file except that setuid and execute bits are not retained. If ''outfile'' or ''name'' is /dev/stdout the result will be written to standard output. ''Uudecode'' ignores any leading and trailing lines. The program can automatically decide which of the both supported encoding schemes are used. !!EXAMPLES 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 !!SEE ALSO compress(1), mail(1), uucp(1), uuencode(5) !!STANDARDS This implementation is compliant with P1003.2b/D11. !!BUGS If more than one file is given to ''uudecode'' and the -o option is given or more than one ''name'' in the encoded files are the same the result is probably not what is expected. The encoded form of the file is expanded by 37% for UU encoding and by 35% for base64 encoding (3 bytes become 4 plus control information). !!HISTORY The ''uuencode'' command appeared in [BSD] 4.0. ----
