.SH NAME
|
||||
.BR rm
|
||||
\- remove directory entries
|
||||
.SH SYNOPSIS
|
||||
.BR rm
|
||||
.RB [ -f | -i ]
|
||||
.RB [ -dPRr ]
|
||||
.IR file ...
|
||||
.SH DESCRIPTION
|
||||
The
|
||||
.BR rm
|
||||
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:
|
||||
.IP \fB-d\fR
|
||||
Attempt to remove directories as well as other types of files.
|
||||
.IP \fB-f\fR
|
||||
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
|
||||
.BI -f
|
||||
option overrides any previous
|
||||
.BI -i
|
||||
options.
|
||||
.IP \fB-i\fR
|
||||
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
|
||||
.BI -i
|
||||
option overrides any previous
|
||||
.BI -f
|
||||
options.
|
||||
.IP \fB-P\fR
|
||||
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.
|
||||
.IP \fB-R\fR
|
||||
Attempt to remove the file hierarchy rooted in each file argument.
|
||||
The
|
||||
.BI -R
|
||||
option implies the
|
||||
.BI -d
|
||||
option.
|
||||
If the
|
||||
.BI -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.
|
||||
.IP \fB-r\fR
|
||||
Equivalent to
|
||||
.BR -R .
|
||||
.PP
|
||||
It is an error to attempt to remove the files ``.'' and ``..''.
|
||||
.PP
|
||||
The
|
||||
.BR rm
|
||||
utility exits 0 if all of the named files or file hierarchies were removed,
|
||||
or if the
|
||||
.BI -f
|
||||
option was specified and all of the existing files or file hierarchies were
|
||||
removed.
|
||||
If an error occurs,
|
||||
.BR rm
|
||||
exits with a value >0.
|
||||
.SH NOTE
|
||||
The
|
||||
.BR rm
|
||||
command uses
|
||||
.BR getopt (3)
|
||||
to parse its arguments, which allows it to accept
|
||||
the
|
||||
.BI --
|
||||
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
|
||||
.RB ( - ).
|
||||
For example:
|
||||
.nf
|
||||
rm -- -filename
|
||||
.fi
|
||||
The same behavior can be obtained by using an absolute or relative
|
||||
path reference. For example:
|
||||
.nf
|
||||
rm /home/user/-filename
|
||||
rm ./-filename
|
||||
.fi
|
||||
This is useful for commands that do not use
|
||||
.BR getopt (3)
|
||||
to parse the command line arguments.
|
||||
.SH SEE ALSO
|
||||
.BR rmdir (1),
|
||||
.BR unlink (2),
|
||||
.BR fts (3),
|
||||
.BR getopt (3)
|
||||
.SH BUGS
|
||||
The
|
||||
.BI -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.
|
||||
.SH COMPATIBILITY
|
||||
The
|
||||
.BR rm
|
||||
utility differs from historical implementations in that the
|
||||
.BI -f
|
||||
option only masks attempts to remove non-existent files instead of
|
||||
masking a large variety of errors.
|
||||
.PP
|
||||
Also, historical
|
||||
implementations prompted on the standard output,
|
||||
not the standard error output.
|
||||
.SH STANDARDS
|
||||
The
|
||||
.BR rm
|
||||
command is expected to be
|
||||
POSIX-2
|
||||
compatible.
|
||||
.SH VERSION
|
||||
This manual page documents GNO
|
||||
.BR rm
|
||||
version 1.0.
|
||||
.SH ATTRIBUTIONS
|
||||
This command was ported from FreeBSD source code
|
||||
for distribution with GNO/ME 2.0.6.
|
||||
.SH HISTORY
|
||||
This is the first version of
|
||||
.BR rm
|
||||
to be released with GNO.
|
||||
Previously, the file removal function was accomplished
|
||||
via an option to the
|
||||
.BR cp
|
||||
command.
