For example:</p><div class="example"><p><code> CustomLog "|bin/rotatelogs /var/logs/logfile 86400" common</code></p></div> <p>This creates the files /var/logs/logfile.nnnn where nnnn is the system time at which the log nominally starts (this time will always be a multiple of the rotation time, so you can synchronize cron scripts with it). At the end of each rotation time (here after 24 hours) a new log is started.</p><div class="example"><p><code> CustomLog "|bin/rotatelogs /var/logs/logfile 5M" common</code></p></div> <p>This configuration will rotate the logfile whenever it reaches a size of 5 megabytes.</p> <div class="example"><p><code> ErrorLog "|bin/rotatelogs /var/logs/errorlog.%Y-%m-%d-%H_%M_%S 5M"</code></p></div> <p>This configuration will rotate the error logfile whenever it reaches a size of 5 megabytes, and the suffix to the logfile name will be created of the form <code>errorlog.YYYY-mm-dd-HH_MM_SS</code>.</p> </div><div id="quickview"><ul id="toc"><li><img alt="" src="../images/down.gif" /> <a href="#synopsis">Synopsis</a></li><li><img alt="" src="../images/down.gif" /> <a href="#options">Options</a></li><li><img alt="" src="../images/down.gif" /> <a href="#portability">Portability</a></li></ul></div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div><div class="section"><h2><a name="synopsis" id="synopsis">Synopsis</a></h2> <p><code><strong>rotatelogs</strong> [ -<strong>l</strong> ] <var>logfile</var> [ <var>rotationtime</var> [ <var>offset</var> ]] | [ <var>filesize</var>M ]</code></p></div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div><div class="section"><h2><a name="options" id="options">Options</a></h2><dl><dt><code>-l</code> (<em>2.0.51 and later</em>)</dt><dd>Causes the use of local time rather than GMT as the base for theinterval.
