You could at the start of the shell write an 'in-process flag' (simply create file with a specific name).
As the final step in the process, when completed successfully, delete that file. Then ..... If [exists(file)] - you know the process failed. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ralph Melia Sent: Wednesday, July 21, 2004 7:39 PM To: [EMAIL PROTECTED] Subject: [U2] [UD] Returning data to ksh I'm working on a project that involves integrating our (UD 5.2 on AIX) programs into a job stream via ksh scripts. And I need a way of communicating back to the calling shell whether the unidata process (program) completed successfully or not. The relevent part of the shell would look something like: $UDTBIN/udt program parameters if [ it failed ]; then do something I'm thinking that there must be a simple solution, but I'm drawing a blank.
