need help on bash scripting

stympman · 10-20-2008, 04:33 PM

I have two things that I can't figure out.

1. How to a get a bash script to print out only it's own PID

2. How do I send a signal to a running script. More specifically signal SIGHUP(1), SIGINT(2) and SIGTERM(15)

Thanks

kill -HUP pid
kill -INT pid
kill -TERM pid

Apparently $$ contains the pid of the current script and $! contains the pid of the last background process started from within the script.

Hi,

Sounds like homework to me!
