awk itself is very portable. Just be careful about what subset of the language you use; there's "old awk" and "new awk", and I'm not quite sure that there aren't a few weird ancient holdouts that still have only old awk. http://www.opengroup.org/onlinepubs/007904975/utilities/awk.html describes some of the differences. Also avoid GNU extensions (described in gawk(1)) if you want to be portable. > > AFAIK POSIX requires it. > > I'm really not an expert in Unix, and it's standards, but IIRC Windows > NT also passed the POSIX tests, and became POSIX compliant.

In particular, Windows NT (to my knowledge) only implements POSIX.1, the C language API, not POSIX.2 which covers shell utilities like awk. The first hit for "Windows NT POSIX compliance" on Google is http://msdn.microsoft.com/archive/en-us/dnarwbgen/html/msdn_posix.asp, which seems to cover this. -- Colin Watson [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
