The s6-rc-dryrun internal program
s6-rc-dryrun is a command wrapper and nullifier, roughly
equivalent to the Unix echo command. When run, it
simply prints its arguments to stdout.
s6-rc-dryrun is not meant to be used directly; it is
internally called by
s6-rc when given the -n
option. When a dry-running s6-rc instance wants to change the
system state by spawning a command cmd, it spawns
s6-rc-dryrun cmd instead, which allows the user
to see what would have been done without actually running the
s6-rc-dryrun [ -v verbosity ] [ -t timeout ] cmd...
- s6-rc-dryrun prints its name, a colon, a space, and
the space-separated list of its arguments to stdout.
- It then waits for timeout milliseconds, then
- -v verbosity : if verbosity
is 0, s6-rc-dryrun will not print anything to stdout. Default is 1.
- -t timeout : sleep for timeout
milliseconds before exiting. Default is 1000, but when invoked by
s6-rc, it will be the value of the
dryruntimeout argument to the -n option. This is
used to simulate a start or stop script that does not complete
