.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 flag
|
||||||
|
.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 with random data, before they are deleted.
|
||||||
|
Some care is taken to ensure that the data are actually written to
|
||||||
|
disk, but this cannot be guaranteed, even on traditional filesystems;
|
||||||
|
on log-structured filesystems or if any block-journaling scheme is
|
||||||
|
in use, this option is completely useless.
|
||||||
|
If the file cannot be
|
||||||
|
overwritten, it will not be removed.
|
||||||
|
.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
|
||||||
|
Cause
|
||||||
|
.Nm
|
||||||
|
to be verbose, showing files as they are processed.
|
||||||
|
.It Fl W
|
||||||
|
Attempts 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 ``.'' and ``..''.
|
||||||
|
.Sh EXIT STATUS
|
||||||
|
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 \*[Gt]0.
|
||||||
|
.Sh EXAMPLES
|
||||||
|
.Nm
|
||||||
|
uses
|
||||||
|
.Xr getopt 3
|
||||||
|
standard argument processing.
|
||||||
|
Removing filenames that begin with a dash
|
||||||
|
.Pq e.g., Ar -file
|
||||||
|
in the current directory which might otherwise be taken as option flags to
|
||||||
|
.Nm
|
||||||
|
can be accomplished as follows:
|
||||||
|
.Pp
|
||||||
|
.Ic "rm -- -file"
|
||||||
|
.Pp
|
||||||
|
or
|
||||||
|
.Pp
|
||||||
|
.Ic "rm ./-file"
|
||||||
|

|
||||||
|
.Xr undelete 2 ,
|
||||||
|

|
||||||
|
.Xr symlink 7
|
||||||
|
.Sh BUGS
|
||||||
|
The
|
||||||
|
.Fl P
|
||||||
|
option assumes that the underlying file system is a fixed-block file
|
||||||
|
system.
|
||||||
|
FFS is a fixed-block file system, LFS is not.
|
||||||
|
In addition, only regular files are overwritten, other types of files
|
||||||
|
are not.
|
||||||
|
Recent research indicates that as many as 35 overwrite passes with
|
||||||
|
carefully chosen data patterns may be necessary to actually prevent
|
||||||
|
recovery of data from a magnetic disk.
|
||||||
|
Thus the
|
||||||
|
.Fl P
|
||||||
|
option is likely both insufficient for its design purpose and far
|
||||||
|
too costly for default operation.
|
||||||
|
However, it will at least prevent the recovery of data from FFS
|
||||||
|
volumes with
|
||||||
|
.Xr fsdb 8 .
|
||||||
|
.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.
|
||||||
|
.Pp
|
||||||
|
Also, historical
|
||||||
|
.Bx
|
||||||
|
implementations prompted on the standard output,
|
||||||
|
not the standard error output.
|
||||||
|
.Sh STANDARDS
|
||||||
|
The
|
||||||
|
.Nm
|
||||||
|
utility is expected to be
|
||||||
|
.St -p1003.2
|
||||||
|
compatible.
|
||||||
|
The
|
||||||
|
.Fl v
|
||||||
|
option is an extension.
|
||||||
|
.Pp
|
||||||
|
The
|
||||||
|
.Fl P
|
||||||
|
option attempts to conform to U.S. DoD 5220-22.M, "National Industrial
|
||||||
|
Security Program Operating Manual" ("NISPOM") as updated by Change
|
||||||
|
2 and the July 23, 2003 "Clearing \*[Am] Sanitization Matrix".
|
||||||
|
However, unlike earlier revisions of NISPOM, the 2003 matrix imposes
|
||||||
|
requirements which make it clear that the standard does not and
|
||||||
|
can not apply to the erasure of individual files, in particular
|
||||||
|
requirements relating to spare sector management for an entire
|
||||||
|
magnetic disk.
|
||||||
|
.Em Because these requirements are not met, the
|
||||||
|
.Fl P
|
||||||
|
.Em option does not conform to the standard .

* non-snapshotted FFS filesystems using fsdb(8). Really. No more. Only
|

|

|
*
|
||||||
|
* A note on standards: U.S. DoD 5220.22-M "National Industrial Security
|
||||||
|
* Program Operating Manual" ("NISPOM") is often cited as a reference
|
||||||
|
* for clearing and sanitizing magnetic media. In fact, a matrix of
|
||||||
|
* "clearing" and "sanitization" methods for various media was given in
|
||||||
|
* Chapter 8 of the original 1995 version of NISPOM. However, that
|
||||||
|
* matrix was *removed from the document* when Chapter 8 was rewritten
|
||||||
|
* in Change 2 to the document in 2001. Recently, the Defense Security
|
||||||
|
* Service has made a revised clearing and sanitization matrix available
|
||||||
|
* in Microsoft Word format on the DSS web site. The standardization
|
||||||
|
* status of this matrix is unclear. Furthermore, one must be very
|
||||||
|
* careful when referring to this matrix: it is intended for the "clearing"
|
||||||
|
* prior to reuse or "sanitization" prior to disposal of *entire media*,
|
||||||
|
* not individual files and the only non-physically-destructive method of
|
||||||
|
* "sanitization" that is permitted for magnetic disks of any kind is
|
||||||
|
* specifically noted to be prohibited for media that have contained
|
||||||
|
* Top Secret data.
|
||||||
|
*
|
||||||
|
* It is impossible to actually conform to the exact procedure given in
|
||||||
|
* the matrix if one is overwriting a file, not an entire disk, because
|
||||||
|
* the procedure requires examination and comparison of the disk's defect
|
||||||
|
* lists. Any program that claims to securely erase *files* while
|
||||||
|
* conforming to the standard, then, is not correct. We do as much of
|
||||||
|
* what the standard requires as can actually be done when erasing a
|
||||||
|
* file, rather than an entire disk; but that does not make us conformant.
|
||||||
|
*
|
||||||
|
* Furthermore, the presence of track caches, disk and controller write
|
||||||
|
* caches, and so forth make it extremely difficult to ensure that data
|
||||||
|
* have actually been written to the disk, particularly when one tries
|
||||||
|
* to repeatedly overwrite the same sectors in quick succession. We call
|
||||||
|
* fsync(), but controllers with nonvolatile cache, as well as IDE disks
|
||||||
|
* that just plain lie about the stable storage of data, will defeat this.
|
||||||
|
*
|
||||||
|
* Finally, widely respected research suggests that the given procedure
|
||||||
|
* is nowhere near sufficient to prevent the recovery of data using special
|
||||||
|
* forensic equipment and techniques that are well-known. This is
|
||||||
|
* presumably one reason that the matrix requires physical media destruction,
|
||||||
|
* rather than any technique of the sort attempted here, for secret data.
|
||||||
|
*
|
||||||
|
* Caveat Emptor.
|
||||||
|
*
|
||||||
|
* rm_overwrite will return 0 on success.

|
||||||
|
.Nm
|
||||||
|
.Op Fl p
|
||||||
|
.Ar directory ...
|
||||||
|
.Sh DESCRIPTION
|
||||||
|
The rmdir utility removes the directory entry specified by
|
||||||
|
each
|
||||||
|
.Ar directory
|
||||||
|
argument, provided it is empty.
|
||||||
|
.Pp
|
||||||
|
Arguments are processed in the order given.
|
||||||
|
In order to remove both a parent directory and a subdirectory
|
||||||
|
of that parent, the subdirectory
|
||||||
|
must be specified first so the parent directory
|
||||||
|
is empty when
|
||||||
|
.Nm
|
||||||
|
tries to remove it.
|
||||||
|
.Pp
|
||||||
|
The following option is available:
|
||||||
|
.Bl -tag -width Ds
|
||||||
|
.It Fl p
|
||||||
|
Each
|
||||||
|
.Ar directory
|
||||||
|
argument is treated as a pathname of which all
|
||||||
|
components will be removed, if they are empty,
|
||||||
|
starting with the last most component.
|
||||||
|
(See
|
||||||
|
.Xr rm 1
|
||||||
|
for fully non-discriminant recursive removal.)
|
||||||
|
.El
|
||||||
|
.Sh EXIT STATUS
|
||||||
|
The
|
||||||
|
.Nm
|
||||||
|
utility exits with one of the following values:
|
||||||
|
.Bl -tag -width Ds
|
||||||
|
.It Li \&0
|
||||||
|
Each directory entry specified by a dir operand
|
||||||
|
referred to an empty directory and was removed
|
||||||
|
successfully.
|
||||||
|
.It Li \&\*[Gt]\&0
|
||||||
|
An error occurred.
|
||||||
|
.El
|
||||||
|
.Sh SEE ALSO
|
||||||
|
.Xr rm 1
|
||||||
|
.Sh STANDARDS
|
||||||
|
The
|
||||||
|
.Nm
|
||||||
|
utility is expected to be
|
||||||
|
.St -p1003.2
|
||||||
|
compatible.

Replace our native rm and rmdir with NetBSD version.
|
||||||
|
|
||||||
|
As our native rm is a hard link to cp, simply overwriting rm with

||||||
|
the new version would cause mv, cp, ln, etc to stop working.
|
||||||
|

Do this BEFORE a 'make world':
