remove directory entries
utility attempts to remove the
non-directory type files specified on the command line. If the permissions of
the file do not permit writing, and the standard input device is a terminal,
the user is prompted (on the standard error output) for confirmation.
The options are as follows:
- Attempt to remove directories as well as other types of files.
- Attempt to remove the files without prompting for confirmation, regardless
of the file's 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
- Request confirmation before attempting to remove each file, regardless of
the file's permissions, or whether or not the standard input device is a
-i option overrides any
- Attempt to overwrite regular writable files before deleting them. Files
are overwritten once with a random pattern. Files with multiple links will
be unlinked but not 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 directory (and its contents) are
processed. If the user does not respond affirmatively, the file hierarchy
rooted in that directory is skipped.
- Equivalent to
- Display each file name after it was removed.

option assumes that both the
underlying file system and storage medium write in place. This is true for the
FFS and MS-DOS file systems and magnetic hard disks, but not true for most
flash storage. In addition, only regular files are overwritten; other types of
files are not.
