Background PID introspection

[litagliano]

Hi to all,

my problem refers to $$ behaviour. If I have this script, in which I try to read bgFunc's PID from itself:

#!/bin/sh

bgFunc()
{
   echo "bgFunc PID: $$"
}


#main

bgFunc &
echo "spawned bgFunc PID: $!"
echo "main PID: $$"

PID returned from $$ in bgFunc is equal to main's PID, and NOT to "spawned bgFunc PID".

How can I read bgFunc's PID from bgFunc itself?

bigfunc() is a shell function, not a process, so $! will naturally return the shell's pid. IE, $! will equal $$.
