wrote that dsw "was a desperation tool designed to clean up files with unutterable names". The command is available as a separate package for Microsoft Windows as part of the UnxUtils collection of native Win32 ports of common GNU Unix-like utilities. KolibriOS includes an implementation of the command. The command has also been ported to the IBM i operating system. Syntax rm deletes the file specified after options are added. Users can use a full path or a relative file path to specify the files to delete. rm doesn't delete a directory by default.rm foo deletes the file "foo" in the directory the user is currently in. rm, like other commands, uses options to specify how it will behave: -r, "recursive," which removes directories, removing the contents recursively beforehand (so as not to leave files without a directory to reside in). -i, "interactive" which asks for every deletion to be confirmed. -f, "force," which ignores non-existent files and overrides any confirmation prompts (effectively canceling -i), although it will not remove files from a directory if the directory is write-protected. -v, "verbose," which prints what rm is doing onto the terminal -d, "directory," which deletes an empty directory, and only works if the specified directory is empty. --one-file-system, only removes files on the same file system as the argument, and will ignore mounted file systems. rm can be overlain by a shell alias (C shell alias, Bourne shell or Bash) function of "rm -i" so as to avoid accidental deletion of files. If a user still wishes to delete a large number of files without confirmation, they can manually cancel out the -i argument by adding the -f option (as the option specified later on the expanded command line "rm -i -f" takes precedence). Unfortunately this approach generates dangerous habits towards the use of wildcarding, leading to its own version of accidental removals. rm -rf (variously, rm -rf /, rm -rf *, and others) is frequently used in jokes and anecdotes about Unix disasters, such as the loss of many files during the production of film Toy Story 2 at Pixar. The rm -rf / variant of the command, if run by a superuser, would cause every file accessible from the present file system to be deleted from the machine. rm is often used in conjunction with xargs to supply a list of files to delete: xargs rm < filelist Or,
