I have a bash
script which is run via at
, I run it like
echo "bash /path/to/my/script.sh" | at -M now
because I want it
to run detached.
When the script is spawned, immediately I see 2 instances (ps
), and
even after my script completes successfully, another instance just
wont terminate. It will get reparented to pid 1
and just keeps doing
wait ( strace
shows wait4(-1...
).
I am not able to figure out why or how this second instance is forked!
When I run the script without at
, I don’t see the second process.
Any hints/tips to debug this ?
Thanks.
