Ron,

>>typeset -i rc=`path_to_script [arg1 ...]`

I think I get it?
This line appears to retrieve RC to imp_wrapper.sh, from imp_script.sh and interrogate? [Reidy, Ronald] Yes. The code between the back ticks (` ... `) executes in a sub shell. when the sub shell terminates, it's return code is saved into the variable rc (which is an integer type). But what (line/code) executes the imp_script.sh?...the same line? [Reidy, Ronald] Yes.

PS If you solve this one for me too I going have to start referencing you in my shell script and crediting you in my status reports! ;o)
[Reidy, Ronald] Cool. Do I get on the payroll also ;D

Thanks,

Chris Marquez

to trap the error code:

typeset -i rc=`path_to_script [arg1 ...]` if [[ $rc -ne 0 ]]; then
# exit appropriately
fi

Subject: PART II: - Beyond a basic Oracle EXP/IMP shell script: Error Handling & Exit Status?

In my original quest for help I was working with one script. (btw with you help/code I did complete this task...works well, thanks!)

Now I have a new problem that I do not know how to deal with. I have a wrapper script involved this time.

Something like this;

imp_wrapper.sh
...

#RUN THIS SCRIPT
script1.sh

#RUN THIS FUNCTION
do func1

#RUN THE IMP SCRIPT
imp_script.sh

#RUN THIS SCRIPT
script2.sh

#RUN THIS FUNCTION
do func2

# RETURN CODE: Set next Return Code.
RC=$?
echo 'RETURN CODE' >> $log_file 2>&1
echo $RC >> $log_file

My imp_script.sh has "trap" code and "RETURN CODE" syntax/value also in the script.

But I need to be able to STOP/EXIT/END the parent script; imp_wrapper.sh and set $?=1 when child scrip; imp_script.sh fails with RC=1?

Meaning if import.sh; RC=1, then I want imp_wrapper.sh; RC=1 immediately and exit?

This confuses me and I have no idea how to pass child (exit) RC to the parent script.

Thanks in advance,
