41 .Nd encode/decode a binary file
53 are used to transmit binary files over transmission mediums
54 that do not support other than simple
61 (or by default the standard input) and writes an encoded version
62 to the standard output.
63 The encoding uses only printing
65 characters and includes the
66 mode of the file and the operand
74 files (or by default, the standard input) into the original form.
75 The resulting file is named
77 and will have the mode of the original file except that setuid
78 and execute bits are not retained.
80 ignores any leading and trailing lines.
82 The following options are available for
86 Decode more than one uuencode'd file from
90 Do not overwrite files.
94 and write output to standard output.
96 Do not strip output pathname to base filename.
99 deletes any prefix ending with the last slash '/' for security
103 The following example packages up a source tree, compresses it,
104 uuencodes it and mails it to a user on another system.
107 is run on the target system, the file ``src_tree.tar.Z'' will be
108 created which may then be uncompressed and extracted into the original
111 .Bd -literal -offset indent -compact
112 tar cf \- src_tree \&| compress \&|
113 uuencode src_tree.tar.Z \&| mail sys1!sys2!user
116 The following example unpack all uuencode'd
117 files from your mailbox into your current working directory.
119 .Bd -literal -offset indent -compact
123 The following example extract a compress'ed tar
124 archive from your mailbox
126 .Bd -literal -offset indent -compact
127 uudecode -p < $MAIL | zcat | tar xfv -
136 The encoded form of the file is expanded by 35% (3 bytes become 4 plus
137 control information).
