anyone can help me ?

things get better, but I find if I change the "sleep 1" to "sleep 100", after 5s, it doesn't kill the "sleep 100", and looks it doesn't kill the mainpid too, so the cleanup doesn't execute.

BTW,...

That's not what I wanted, I just give the example that I need to exit 0 intentionally, can you help me to re-write the cmd function
to achieve this ?

cmd()
{
results=`eval $* 2>&1`
val=$? #return the $* execution value
}



cmd "cd /home/tom || exit 0"
