Attempt to remove directories as well as other types of files.
Attempt to remove the files without prompting for confirmation, regardless of the files permissions. If the file does not exist, do not display a diagnostic message or modify the exit status to reflect an error. The -f option overrides any previous -i options.
Request confirmation before attempting to remove each file, regardless of the files permissions, or whether or not the standard input device is a terminal. The -i option overrides any previous -f options.
Request confirmation once if more than three files are being removed or if a directory is being recursively removed. This is a far less intrusive option than -i yet provides almost the same level of protection against mistakes.
Overwrite regular files before deleting them. Files are overwritten three times, first with the byte pattern 0xff, then 0x00, and then 0xff again, before they are deleted. Specifying this flag for a read only file will cause rm to generate an error message and exit. The file wil not be removed or overwritten.
Attempt to remove the file hierarchy rooted in each file argument. The -R option implies the -d option. If the -i option is specified, the user is prompted for confirmation before each directorys contents are processed (as well as before the attempt is made to remove the directory). If the user does not respond affirmatively, the file hierarchy rooted in that directory is skipped.
Equivalent to -R .
Be verbose when deleting files, showing them as they are removed.
Attempt to undelete the named files. Currently, this option can only be used to recover files covered by whiteouts.
The rm utility removes symbolic links, not the files referenced by the links.
It is an error to attempt to remove the files /, . or ...
When the utility is called as unlink, only one argument, which must not be a directory, may be supplied. No options may be supplied in this simple mode of operation, which performs an unlink(2) operation on the passed argument.
The rm utility exits 0 if all of the named files or file hierarchies were removed, or if the -f option was specified and all of the existing files or file hierarchies were removed. If an error occurs, rm exits with a value >0.
