The encoding uses only printing ASCII characters and includes the mode of the file and the operand .I name for use by .IR uudecode . .PP .I Uudecode transforms .I uuencoded files (or by default, the standard input) into the original form. The resulting file is named .IR name and will have the mode of the original file except that setuid and execute bits are not retained. .I Uudecode ignores any leading and trailing lines. .SH EXAMPLES The following example packages up a source tree, compresses it, uuencodes it and mails it to a user on another system. When .I 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. .sp .in +5 tar cf - src_tree | compress | uuencode src_tree.tar.Z | mail sys1!sys2!user .sp .SH SEE ALSO compress(1), mail(1), uucp(1), uuencode.format(5) .SH BUGS The encoded form of the file is expanded by 35% (3 bytes become 4 plus control information).
