I started to list my favourite features (procedures, splitting, pattern
matching, case) of rc, but I was just replicating the man page.
I like rc because I can use it and understand scripts I haven't written,
it is surprise free.
I've also recently started making more use of signals.
I spawn firefox to grab it's output with inferno via vnc but sometimes
the page never finishes loading so I have to kill it something like this :
fn sigalrm {
kill_firefox_sleep_and_screengrab
}
sleep 200 && kill -ALRM $pid
firefox $url &
screengrab_when_appropriate &
wait
kill -ALRM $pid
