[ale] bash pid

[Jim Kinney]

I have a bash script that performs a sequence of tasks. I would like to be
able to get the pid of the individual tasks for probable kill needs.

For example:

#!/bin/bash

my_pid=$$  # get's the pid of the main script

function do_sleep {
 # sleeps in certain conditions
 if [ <condition> ]; then sleep 2m; fi
}

for poo in $( <generated list of crap>); do
 psql -c "vacuum freeze poo;"
 do_sleep
done

So I need to be able to get the pid of the sleep and the psql. $! will give
the pid of a backgrounded shell process but that's not making sense in the
psql call case. Could run a ps |grep <cmd> and strip out the extra or even
pidof <cmd> but all require putting things in a background state.
