UNIX for Beginners Questions & Answers

Hi @drysdalk , its -bash

Hi,

OK, great. That's fine then, the supplied code should definitely work. So if you can answer the other questions (about how you're attempting to identify the abnormal termination of the script, and why you believe you can't detect this) we can take things from there.

im calling the script from control-m scheduler
abnormal termination of the script will be detected with exit 1 or 2 or 5. Successful is exit 0
with the provided changes, it is mailing till End_of_day.log present but job didn't abend.

Hi,

Hmm, I'm sorry, I don't know what else to suggest at this point. You could maybe try adding some debugging code to capture the output if you can do that, to see when the abend variable is being set, and what exit command your script is attempting to do.

But if you have made the changes I suggested (or some variation thereof), there can't be any way that the script will fail to do abend=1 after sending the mail (unless the very act of sending the mail causes some kind of uncontrollable crash, I suppose, but that's unlikely to say the least), and likewise there can't be any way it will fail to do an exit 1 if abend is set at exit time.

If I only knew how you use the verb "abend" - my dictionary tells me "system / program crash" or "abnormal termination".

Why not a function? try

Code:

proc2eod ()     { XTCD=1
                  until [ -e End_of_day.log ]
                    do  [ -s file.txt ] && XTCD=0 && echo mail your stuff
                        sleep 3
                    done
                  return $XTCD
                }
