I have a weird situation which looks as though $$ is broken in sh.
This is on a 5.2 amd64 machine.
My rc.local begins with some code to adjust resource limits:
for pid in 1 $thispid
...use sysctl -w proc.$pid.rlimit.etc...
However, daemons started later in /etc/rc.local were getting the
original resource limits, even though the sysctl -w commands were
printing out suitable changed limits for PIDs 1 and 2.
I finally resorted to the sledgehammer of running
"ktrace -i -d -f ... -p 1" at the very beginning of rc.local, with
"sleep 5" and "ktrace -C" at the end. The resulting ktrace file made
it clear the script was being run by PID 279, not 2. Checking with ps,
I see four "sh /etc/rc autoboot" processes, one of which is PID 2 and
another of which is PID 279.
The real question I have here is, why is $$ in rc.local giving me the
wrong value? As I understand it, it should give me the process ID of
the process running the script, not the process ID of a different
process somewhere up the process parenting tree.
Perhaps more importantly, what can I do to fix it? Failing that, is
there some other tool I can use to give me the correct PID as a
