Regex match not working

[Joao Santos]

I'm trying to force a system to have only one getty, on tty1, but i'm hitting some road blocks.

This is the promise right now:

  processes:

    "getty (/dev/tty[2-9])"

      process_stop => "/sbin/initctl stop tty TTY=$(match.1)",

      comment => "Process getty $(match.1) should be stopped";

The problem is that initctl is being called with the text "$(match.1)" instead of, for example, "/dev/tty5". The getty HAS to be stopped with this command, killing it will only get it restarted by the init system.

Any ideas?

I see the same problem with 3.3.5.  Even match.0 is not expanded.  Yet, there are matched indicated in verbose mode.

stop tty TTY=${match.1}

You used curly braces. Shouldn't they be parenthesis ?

stop tty TTY=${match.1}

[neilhwatson]

{} and () are inter-changable.
