This is probably a failure in my understanding of trap or of function invocation. I'd really appreciate if someone could explain. This is Solaris 10, but I don't think it matters.
Code:
#!/usr/bin/ksh
trap 'cleanUp $@' exit
function cleanUp
{
print "I got called"
}
function check
{
exit 40
}
function check2
{
check
}
check2
The trap (cleanUp) never gets called. If I invoke check directly, it does, and if I add the trap to check2, it does, but not as written above. Why?

Code:
you have to use this:-
trap 'commands ....commands' EXIT
# EXIT is the name of the signal generated upon exit from a script
another way to use trap see example below:-
trap 'rm -f ${TMPFILE} ; exit' 0 1 2 3 15
# ==> Signals: HUP INT (Ctl-C) QUIT TERM
# ==> Delete tempfile in case of abnormal exit from script.
I just tried this on Solaris and the trap isn't called with ksh from check2.
But if I use bash or sh it is taken!
It works fine in Linux with ksh.
I'm using Solaris x86. Ksh couldn't be different on that to other platforms... could it. Which are you using ahmad?

may be because you are using
exit 40
use :
trap 'commands....' 40

Code:
Did you try the below syntax
trap "{ cleanUp "$@" }" exit
where you need to quote the variables... kindly try it..
