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 ...
Changes file security context chgrp: Changes file group ownership chown: Changes file ownership chmod: Changes the permissions of a file or directory cp: Copies a file or directory dd: Copies and converts a file df: Shows disk free space on file systems dir: Is exactly like "ls -C -b". (Files are by default listed in columns and sorted vertically.)
Perl Programming Documentation, also called perldoc, is the name of the user manual for the Perl 5 programming language. It is available in several different formats, including online in HTML and PDF .
In source code files, the documentation is generally placed after the __END__ marker (which also helps syntax highlighting in some editors to display it as comments). Pod can easily be converted to other formats, for example some of the various Wiki formats like: WikiWikiWeb , Kwiki , TWiki , UseModWiki , TiddlyWiki , Textile , MediaWiki ...

This is a list of POSIX (Portable Operating System Interface) commands as specified by IEEE Std 1003.1-2024, which is part of the Single UNIX Specification (SUS). These commands can be found on Unix operating systems and most Unix-like operating systems.
The rm (delete file) command removes the link itself, not the target file. Likewise, the mv command moves or renames the link, not the target. The cp command has options that allow either the symbolic link or the target to be copied. Commands which read or write file contents will access the contents of the target file.
rm (short for remove) is a basic command on Unix and Unix-like operating systems used to remove objects such as computer files, directories and symbolic links from file systems and also special files such as device nodes, pipes and sockets, similar to the del command in MS-DOS, OS/2, and Microsoft Windows.
