Query on a shell script logic

tipsy · #1 (**permalink**) 06-29-2006

Hello people,
I am new to shell scripting and hoping to get a quick answer to my query.
I am writing a simple script which needs to call an executale which generates an output file. Once the output file is generated I have to do a couple of more task with that file. The executable ideally takes 2 to 3 minutes to finish execution.
My question is
- Should I call the executable & once done look for the output file to do the next steps.
Or
- Should I run the executable as a backgound process using "&" and then have a loop which will keep checking whether the output file is generated.

Is there any drawbacks with following either of these approaches.

Any inputs would be highly appreciated.

Regards,
Tipsy

If you need the complete output file, just run the executable in the foreground. So much simpler.
