Re: running a DOS batch file from a shell script - script doesn't wait for batch file to complete before continuing
Since you were the only person who was kind enough to take the time to respond
to my initial question, I owe it to you to provide a followup on this subject.
I wrote a few DOS batch files as well as shell scripts to try and
problem. I managed to track down the problem to the Pro/E executable
Depending on whether the "-text" option is provided to pro_batch.bat, it
run the UI executable or the command-line executable pro_batch_t.exe.
The problem seems to come from pro_batch_t.exe. This program apparently
wants to run in the background and therefore it doesn't matter whether you
invoke it from a DOS batch file or a Cygwin shell script, the batch
continue to run before pro_batch_t.exe terminates. The version of Pro/E in
question is Release 20.
To solve my problem, I added two loops to my scripts, one to check for the
presence of the log file pro_batch.log.1 every 5 seconds and upon detecting
it checks every 5 seconds for the keyword "Result" which is the last line of
pro_batch.log.1 when pro_batch_t.exe is completed. It seems to do the job.

Well, I guess I need a simple example then. So far, everything I've
tried works fine.
