RE: Simple bash problem.



Yes I now see it was my silly fault for calling the function "sigtrap" :-(
Changed it to something else and now it works OK.

Thanks for the responses.

Ok, this is really my last followup to myself. Giving this a little
more thought leads me to observe that sigtrap is being caught as part
of your sigspec ... changing the name of your function to something
that isn't legal in the sigspec would probably be a good idea in any
event and then RHEL3 works as you expect.
