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 command.
Interface
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 exits 0.
Options
- -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 immediately.
