Is there a way to create a custom signal in linux. Like lets say when "echo crazy" gets executed in a file? And whenever that signal gets executed, I would stop the process using that signal...
Also I want to use the perl Enbugger with a new signal also. Is there a way to do that?
I found this from <http://metacpan.org/pod/Enbugger>

```
 use Enbugger::OnError qw( USR1 USR2 INT HUP );

```

Where USR1 and USR2 are user defined signals.
