This command provides a moreuser-friendly interface to SCCS and has the following command-line syntax:</p><blockquote><pre class="code">sccs  [<em class="replaceable"><tt>options</em>]  <em class="replaceable">command</em>  [<em class="replaceable">SCCS_flags</em>]  [<em class="replaceable">files</tt></em>]</pre></blockquote><p>In addition to providing all the regular SCCS commands,<tt class="literal">sccs</tt> offers pseudo-commands.  These areeasy-to-use, prebuilt combinations of the regular SCCS commands.<em class="emphasis">options</em> apply only to the <tt class="literal">sccs</tt> interface.<em class="emphasis">command</em> is the SCCS command or pseudo-command to run,and <em class="emphasis">SCCS_flags</em> are specific options passed to the SCCS command being run.</p><p><tt class="literal">sccs</tt> makes it easier to specify files becauseit automatically prepends <tt class="literal">SCCS/s.</tt> to any filename arguments.For example:</p><blockquote><pre class="code"><tt class="userinput"><b>sccs get -e file.c</b></tt></pre></blockquote><p>would be interpreted as:</p><blockquote><pre class="code"><tt class="userinput"><b>get -e SCCS/s.file.c</b></tt></pre></blockquote><p>Thus, when using <tt class="literal">sccs</tt>, you would first make a directorynamed <tt class="literal">SCCS</tt> to hold all the <tt class="literal">s.</tt> SCCS files.</p><a name="unut-ch-18-sect-6.1" /><div class="sect2"><h3 class="sect2">18.7.1.
