Unlink (Unix)
Script error: No such module "about". Template:Lowercase Script error: No such module "Infobox".Template:Template other Script error: No such module "Check for unknown parameters".Script error: No such module "Check for conflicting parameters". 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]
Examples
To delete a file named foo, one could type:
% unlink foo
In PHP, one could use the following function to do the same:
unlink("foo");
The Perl syntax is identical to the PHP syntax, save for the parentheses:
unlink "foo";
In Node.js it is almost the same as the others:
fs.unlink("foo", callback);
In R (with the S language compatibility):
unlink("foo")
#Comment: using the inside argument 'recursive = TRUE', directories can be deleted
Similarly in Python:
os.unlink("foo")
