The uniquename program

uniquename writes a unique file name to stdout.

Interface

     uniquename [ prefix ] [ r ]

• uniquename writes a suitable file name on stdout. The name starts with prefix (which can be a directory), if it is given, and ends with r random printable characters, if r is given. Even if you don't specify a random suffix, the produced name is very difficult to predict.
• Two calls to uniquename are guaranteed never to give the same name.
• uniquename exits 0, or 111 on any error.
