The original AWK had bugs. So New AWK was written to fix those; and I suppose some additional functionality was added while they were at it. I haven't verified it for the case of awk/nawk, but often these kinds of programs end up being a single program that examines its command line to see how it was called; then it behaves accordingly.
It is indeed a mystery as to why the Linux cognoscenti left awk in the distribution, but tossed nawk when -- as they look down their collective nose and wave their collective finger at you -- you should be using gawk. Now there's always the duct tape and bailing wire rig of soft links .... > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] > Sent: Monday, August 04, 2003 1:59 PM > To: Multiple recipients of list ORACLE-L > Subject: RE: One for bash experts.... > > > Yes, there are differences between nawk and awk. > > Scripts written for nawk may not work on awk. > > Don't ask me why, check the man pages. :) > > Jared > > > > > > "Matthew Zito" <[EMAIL PROTECTED]> > Sent by: [EMAIL PROTECTED] > 08/04/2003 11:19 AM > Please respond to ORACLE-L > > > To: Multiple recipients of list ORACLE-L > <[EMAIL PROTECTED]> > cc: > Subject: RE: One for bash experts.... > > > It's looking for the command "nawk" - either find a source > package and > install it, or change your script to call awk instead.
