Trap function by passing arguments?
trap lets you specify an arbitrary command (or sequence of commands), but you have to pass that command as a single argument. For example, this:
trap 'foo bar baz | bip && fred barney ; wilma' SIGINTwill run this:
foo bar baz | bip && fred barney ; wilmawhenever the shell receives SIGINT. In your case, it sounds like you want:
trap '<function> <arg_1> <arg_2>' SIGINT
I'm not sure I understand correctly what you mean, but if you want to make a signal handler call a function and pass it parameters, trap "function arg1 arg2" SIGNAL should work. For example trap "ls -lh /" INT will cause Ctrl+C in your shell to result in ls -lh / (program with 2 args) being called.
