<h1> The s6-softlimit program </h1>
<p>
s6-softlimit changes its process limits, then executes into another program.
</p>
<h2> Interface </h2>
<pre>
s6-softlimit [ -a <em>allmem</em> ] [ -c <em>core</em> ] [ -d <em>data</em> ] [ -f <em>fsize</em> ] [ -l <em>lock</em> ] [ -m <em>mem</em> ] [ -o <em>ofiles</em> ] [ -p <em>proc</em> ] [ -r <em>res</em> ] [ -s <em>stack</em> ] [ -t <em>cpusecs</em> ] <em>prog...</em>
</pre>
<ul>
<li> s6-softlimit parses its options and sets process (soft) resource limits accordingly. </li>
<li> A value of '=' for any option means "set that limit to the hard limit". </li>
<li> Depending on your operating system, an option may do nothing. </li>
<li> When s6-softlimit has modified all the limits successfully, it executes into <em>prog...</em>. </li>
</ul>
<h2> Options </h2>
<ul>
<li> <tt>-a <em>allmem</em></tt> : limit the total available memory to <em>allmem</em> bytes. </li>
<li> <tt>-c <em>core</em></tt> : limit the core file size to <em>core</em> bytes. </li>
<li> <tt>-d <em>data</em></tt> : limit the available heap memory to <em>data</em> bytes. </li>
<li> <tt>-f <em>fsize</em></tt> : limit the file size to <em>fsize</em> bytes. </li>
<li> <tt>-l <em>lock</em></tt> : limit the available locked memory to <em>lock</em> bytes. </li>
<li> <tt>-m <em>mem</em></tt> : limit all types of memory to <em>mem</em> bytes. </li>
<li> <tt>-o <em>ofiles</em></tt> : limit the number of open fds to <em>ofiles</em>. </li>
<li> <tt>-p <em>proc</em></tt> : limit the number of processes to <em>proc</em> (per user). </li>
<li> <tt>-r <em>res</em></tt> : limit the available physical memory to <em>res</em> bytes. </li>
<li> <tt>-s <em>stack</em></tt> : limit the available stack memory to <em>stack</em> bytes. </li>
<li> <tt>-t <em>cpusecs</em></tt> : limit the available CPU time to <em>cpusecs</em> seconds. </li>
</ul>
