<h2 class="chapter">3 <code>lastcomm</code></h2>
<p><code>lastcomm</code> prints out information about previously executed
commands. If no arguments are specified, <code>lastcomm</code> will print
info about all of the commands in the <code>acct</code> file (the
record file). If called with a command name, user name, or tty name,
only records containing those items will be displayed. For example, to
find out which users used command ‘<samp>a.out</samp>’ and which users were
logged into ‘<samp>tty0</samp>’, type:
</p>
<p><code>lastcomm a.out tty0</code>
</p>
<p>This will print any entry for which ‘<samp>a.out</samp>’ or ‘<samp>tty0</samp>’ matches
in any of the record’s fields (command, name, or tty). If you want to
find only items that match ALL of the arguments on the command line, you
must use the ’–strict-match’ option. For example, to list all of the
executions of command ‘<samp>a.out</samp>’ by user ‘<samp>root</samp>’ on terminal
‘<samp>tty0</samp>’, type:
</p>
<p><code>lastcomm --strict-match a.out root tty0</code>
</p>
<p>The order of the arguments is not important.
</p>
<p>For each entry the following information is printed:
</p>
<ul>
<li> command name of the process
</li><li> flags, as recorded by the system accounting routines:
<ul class="no-bullet">
<li>- <strong>S</strong> command executed by super-user
</li><li>- <strong>F</strong> command executed after a fork but without a following exec
</li><li>- <strong>C</strong> command run in PDP-11 compatibility mode (VAX only)
</li><li>- <strong>D</strong> command terminated with the generation of a core file
</li><li>- <strong>X</strong> command was terminated with the signal SIGTERM
</li></ul>
</li><li> the name of the user who ran the process
</li><li> time the process started
</li></ul>
<a name="Flags-2"></a>
<h3 class="section">3.1 Flags</h3>
<p>This program implements the features of regular u*x <code>lastcomm</code> with
a few extra flags. When <code>lastcomm</code> is invoked without arguments,
the output looks like this:
</p><div class="example">
<pre class="example">nslookup jberman ttypb 0.03 secs Tue Feb 16 19:23
