In Unix-like operating systems, unlink is a system call and a command line utility to delete files. The program directly interfaces the system call, which removes the file name and (but not on GNU systems) directories like rm and rmdir. [1]
rmdir: Removes empty directories shred: Overwrites a file to hide its contents, and optionally deletes it sync: Flushes file system buffers touch: Changes file timestamps; creates file truncate: Shrink or extend the size of a file to the specified size vdir: Is exactly like "ls -l -b". (Files are by default listed in long format.)

This includes Perl itself, nearly all publicly released modules, many scripts, most design documents, many articles on Perl.com and other Perl-related web sites, and the Parrot virtual machine. Pod is rarely read in the raw, although it is designed to be readable without the assistance of a formatting tool.
