<h1> The s6-rc-set-status program </h1>
<p>
s6-rc-set-list lists some of, or all, the services of a <a href="repodefs.html#set">set</a>,
along with the <a href="repodefs.html#sub">sub</a> each service is on.
</p>
<h2> Interface </h2>
<pre>
s6-rc-set-list [ -v <em>verbosity</em> ] [ -r <em>repo</em> ] [ -E | -e ] [ -L ] <em>set</em> [ <em>services...</em> ]
</pre>
<ul>
<li> s6-rc-set-list prints the services in set <em>set</em> of repository
<em>repo</em>, one per line, to stdout. If some <em>services...</em> are specified,
it only prints the ones listed; if <em>services...</em> is empty, it prints all the
services in the set. Each line consists of:
<ul>
<li> The name of the service </li>
<li> A slash (<tt>/</tt>) character </li>
<li> The canonical name for the sub the service is in. </li>
</ul> </li>
<li> It exits 0. </li>
</ul>
<h2> Options </h2>
<dl>
<dt> -v <em>verbosity</em>, --verbosity=<em>verbosity</em> </dt>
<dd> Be more or less verbose. The default is <strong>1</strong>, which means
that error messages and warnings will be written to stderr. 0 means that only
error messages will be written, and 2 or more adds informational messages. </dd>
<dt> -r <em>repo</em>, --repository=<em>repo</em> </dt>
<dd> Use the repository in <em>repo</em>, which must exist. Default is
<strong>/var/lib/s6-rc/repository</strong>.
</dd>
<dt> -E, --with-essentials </dt>
<dd> Do not ignore services in the <tt>always</tt> sub, i.e. services marked as
essential. This is the default. </dd>
<dt> -e, --without-essentials </dt>
<dd> Ignore services in the <tt>always</tt> sub: do not print them. </dd>
<dt> -L. --list </dt>
<dd> Do not print <tt>/<em>sub</em></tt> at the end of each line: only print the service names. </dd>
</dl>
<h2> Exit codes </h2>
<dl>
<dt> 0 </dt> <dd> Success. </dd>
<dt> 3 </dt> <dd> Nonexistent set. </dd>
<dt> 100 </dt> <dd> Incorrect usage. </dd>
<dt> 102 </dt> <dd> Invalid repository. </dd>
<dt> 111 </dt> <dd> System call failed. </dd>
</dl>
<h2> Notes </h2>
<ul>
<li> s6-rc-set-status is meant to be used with automation such as
util-linux's <a href="https://man7.org/linux/man-pages/man1/column.1.html">column</a>
for formatting. A slash is used to separate the service name for the sub because
slashes cannot appear in service names. </li>
</ul>
