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] If the file name was the last hard link to the file, the file itself is deleted as soon as no program has it open.[2]
Unlike the rm utility, the unlink utility only accepts one argument, which can be desirable to guard against accidental multi-deletions.[3]
It also appears in the PHP, Node.js, R, Perl and Python standard libraries in the form of the unlink() built-in function. Like the Unix utility, it is also used to delete files.[4][5][6][7]
