When a dry-running s6-rc instance wants to change the +system state by spawning a command <tt><em>cmd</em></tt>, it spawns +<tt>s6-rc-dryrun <em>cmd</em></tt> instead, which allows the user +to see what would have been done without actually running the +command. +</p> + +<h2> Interface </h2> + +<pre> + s6-rc-dryrun [ -v <em>verbosity</em> ] [ -t <em>timeout</em> ] <em>cmd...</em> +</pre> + +<ul> + <li> s6-rc-dryrun prints its name, a colon, a space, and +the space-separated list of its arguments to stdout. </li> + <li> It then waits for <em>timeout</em> milliseconds, then +exits 0. </li> +</ul> + +<h2> Options </h2> + +<ul> + <li> <tt>-v <em>verbosity</em></tt> : if <em>verbosity</em> +is 0, s6-rc-dryrun will not print anything to stdout.
