I can only partly agree. In my case, I am in charge of them boxes. And we are talking a thousand and a bit. However, if I'm not in charge of the box, I do make sure that my script will run with the native tools of whatever unix (well, Linux, FreeBSD, OpenBSD, Solaris) it should run on. I do disagree with regards to a bad habit. It isn't. It's pragmatic. That's what you do if you are in charge of the boxes. And yep, this is really OT now. Cheers, Marian
