Re: Waiting for delayed output after system()

You could check file size as well as existence with -e && -s. That may still not be enough if the file is larger than its write buffer. Do you know what size the output file will be? -s returns the size.

I'm pretty sure lsof won't help over NFS.

First of all thanks for your fast reply. Unfortunately the programs output I'm interested in is only available as a file. And this file doesn't have a fixed size. `lsof` and subsequent `grep` would help over NFS, but I wanted to code portable. So I decided not to use this possibility. I think your idea to check the file size regularly is very good although not 100% sure. I will try this. Thanks again! to.b	[reply] [d/l] [select]
