.Sh NAME

.Nm rm
|
|
.Nd remove directory entries
|
|
.Sh SYNOPSIS
|
|
.Nm rm
|
|
.Op Fl dfiPRrvW
|
|
.Ar file ...
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
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.
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width Fl
|
|
.It Fl d
|
|
Attempt to remove directories as well as other types of files.
|
|
.It Fl f
|
|
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
|
|
.Fl f
|
|
option overrides any previous
|
|
.Fl i
|
|
options.
|
|
.It Fl 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
|
|
.Fl i
|
|
option overrides any previous
|
|
.Fl f
|
|
options.
|
|
.It Fl 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.
|
|
.It Fl R
|
|
Attempt to remove the file hierarchy rooted in each file argument.
|
|
The
|
|
.Fl R
|
|
option implies the
|
|
.Fl d
|
|
option.
|
|
If the
|
|
.Fl i
|
|
option is specified, the user is prompted for confirmation 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.
|
|
.Pp
|
|
.It Fl r
|
|
Equivalent to
|
|
.Fl R .
|
|
.It Fl v
|
|
Be verbose when deleting files, showing them as they are removed.
|
|
.It Fl W
|
|
Attempt to undelete the named files.
|
|
Currently, this option can only be used to recover
|
|
files covered by whiteouts.
|
|
.El
|
|
.Pp
|
|
The
|
|
.Nm
|
|
utility removes symbolic links, not the files referenced by the links.
|
|
.Pp
|
|
It is an error to attempt to remove the files
|
|
.Dq \&.
|
|
or
|
|
.Dq .. .
|
|
.Pp
|
|
The
|
|
.Nm
|
|
utility exits 0 if all of the named files or file hierarchies were removed,
|
|
or if the
|
|
.Fl f
|
|
option was specified and all of the existing files or file hierarchies were
|
|
removed.
|
|
If an error occurs,
|
|
.Nm
|
|
exits with a value >0.
|
|
.Sh NOTE
|
|
The
|
|
.Nm
|
|
command uses
|
|
.Xr getopt 3
|
|
to parse its arguments, which allows it to accept
|
|
the
|
|
.Sq Li --
|
|
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
|
|
.Pq Sq - .
|
|
For example:
|
|
.Dl rm -- -filename
|
|
The same behavior can be obtained by using an absolute or relative
|
|
path reference. For example:
|
|
.Dl rm /home/user/-filename
|
|
.Dl rm ./-filename

|
.Sh BUGS
|
|
The
|
|
.Fl P
|
|
option assumes that the underlying file system is a fixed-block file
|
|
system.
|
|
UFS is a fixed-block file system, LFS is not.
|
|
In addition, only regular files are overwritten, other types of files
|
|
are not.
|
|
.Sh COMPATIBILITY
|
|
The
|
|
.Nm
|
|
utility differs from historical implementations in that the
|
|
.Fl f
|
|
option only masks attempts to remove non-existent files instead of
|
|
masking a large variety of errors.
|
|
The
|
|
.Fl v
|
|
option is non-standard and its use in scripts is not recommended.
|
|
.Pp
|
|
Also, historical
|
|
.Bx
|
|
implementations prompted on the standard output,
|
|
not the standard error output.
|
|
.Sh STANDARDS
|
|
The
|
|
.Nm
|
|
command is almost
|
|
.St -p1003.2
|
|
compatible, except that
|
|
.Tn POSIX
|
|
requires
|
|
.Nm rm
|
|
to act like
|
|
.Xr rmdir 1
|
|
when the
|
|
.Ar file
|
|
specified is a directory. This implementation requires the
|
|
.Fl d
|
|
option if such behavior is desired. This follows the historical
|
|
behavior of
|
|
.Nm
|
|
with respect to directories.
