<strong>Synopsis</strong>
|
||
|
|
|
||
|
|
<p><strong>rm [-f | -i] [-dPRr]</strong> <em>file</em> ...</p>
|
||
|
|
|
||
|
|
<p><strong>Description</strong></p>
|
||
|
|
|
||
|
|
<p>The <strong>rm</strong> utility attempts to remove the
|
||
|
|
non-directory type <em>files</em> specified on the command line. If
|
||
|
|
the permissions of the <em>file</em> do not permit writing, and the
|
||
|
|
standard input device is a terminal, the user is prompted (on
|
||
|
|
standard error) for confirmation.</p>
|
||
|
|
|
||
|
|
<p>The <strong>rm</strong> utility removes symbolic links, not the
|
||
|
|
files referenced by the links.</p>
|
||
|
|
|
||
|
|
<p>It is an error to attempt to remove the files "." and "..".</p>
|
||

<dt><strong>-d</strong></dt>
|
||

<dd>Attempt to remove directories as well as other types of

files.</dd>
|
||
|
|
|
||
|
|
<dt><strong>-f</strong></dt>
|
||
|
|
|
||
|
|
<dd>Attempt to remove the <em>files</em> 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 <strong>-f</strong> option
|
||
|
|
overrides any previous <strong>-i</strong> options.</dd>
|

<dt><strong>-i</strong></dt>
|

<dd>Request confirmation before attempting to remove each <em>
|

|
|
file</em>, regardless of the file's permissions, or whether
|
||
|
|
the standard input device is a terminal. If the response from the
|
||
|
|
standard input begins with the first character for the YES response
|
||
|
|
in the current locale, the <em>file</em> is removed. The <strong>
|

overwritten three times, first with the byte pattern 0xff, then

0x00, and then 0xff again, before they are deleted.</dd>

|

<dd>Attempt to remove the file hierarchy rooted in each <em>

file</em> argument. The <strong>-R</strong> option implies the
|

|
|
<strong>-d</strong> option. If the <strong>-i</strong> 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.</dd>
