rm, unlink - remove directory entries
SYNOPSIS
rm [-dfiPRrvW] file ...
unlink file
DESCRIPTION
The rm utility attempts to remove the non-directory type files specified
on the command line. If the permissions of the file do not permit writ-
ing, and the standard input device is a terminal, the user is prompted
(on the standard error output) for confirmation.
The options are as follows:
-d Attempt to remove directories as well as other types of
files.
-f Attempt to remove the files without prompting for confirma-
tion, regardless of the file's permissions. If the file does
not exist, do not display a diagnostic message or modify the

DESCRIPTION
The rm utility attempts to remove the non-directory type files specified
on the command line. If the permissions of the file do not permit writ-
ing, and the standard input device is a terminal, the user is prompted
(on the standard error output) for confirmation.
The options are as follows:
-d Attempt to remove directories as well as other types of
files.
-f Attempt to remove the files without prompting for confirma-
tion, 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 -i options.
-i Request confirmation before attempting to remove each file,
regardless of the file's permissions, or whether or not the
standard input device is a terminal. The -i option overrides
any previous -f options.
-P 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.
-R 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's contents are processed (as well as
:
before each directory's 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.
-r Equivalent to -R.
-v Be verbose when deleting files, showing them as they are
removed.
-W 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 sim-
ple 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.
NOTE
The rm command uses getopt(3) to parse its arguments, which allows it to
accept the `--' option which will cause it to stop processing flag
options at that point. This will allow the removal of file names that
begin with a dash (`-'). For example:
rm -- -filename
The same behavior can be obtained by using an absolute or relative path
reference. For example:
rm /home/user/-filename
rm ./-filename

BUGS
The -P option assumes that the underlying file system is a fixed-block
file system. In addition, only regular files are overwritten, other types of files are not.
