<h4><a name="tag_04_122_03"></a>DESCRIPTION</h4>
|
|
|
|
<blockquote>
|
|
<p>The <i>rmdel</i> utility shall remove the delta specified by the SID from each named SCCS file. The delta to be removed shall be
|
|
the most recent delta in its branch in the delta chain of each named SCCS file. In addition, the application shall ensure that the
|
|
SID specified is not that of a version being edited for the purpose of making a delta; that is, if a <i>p-file</i> (see <a href=
|
|
"get.html"><i>get</i></a> ) exists for the named SCCS file, the SID specified shall not appear in any entry of the
|
|
<i>p-file</i>.</p>
|
|
|
|
<p>Removal of a delta shall be restricted to:</p>
|
|
|
|
<ol>
|
|
<li>
|
|
<p>The user who made the delta</p>
|
|
</li>
|
|
|
|
<li>
|
|
<p>The owner of the SCCS file</p>
|
|
</li>
|
|
|
|
<li>
|
|
<p>The owner of the directory containing the SCCS file</p>
|
|
</li>
|
|
</ol>

<dd>A pathname of an existing SCCS file or a directory. If <i>file</i> is a directory, the <i>rmdel</i> utility shall behave as

though each file in the directory were specified as a named file, except that non-SCCS files (last component of the pathname does
|
|
not begin with <b>s.</b>) and unreadable files shall be silently ignored.
|
|
|
|
<p>If exactly one <i>file</i> operand appears, and it is <tt>'-'</tt> , the standard input shall be read; each line of the standard
|
|
input is taken to be the name of an SCCS file to be processed. Non-SCCS files and unreadable files shall be silently ignored.</p>
