Step 1: verify that the $awkcmd variable has the right data in it. i.e.,
should show nawk.
Then verify that nawk is in the PATH variable of the process running the code:
Do that before playing with the awk code itself.
The awk code is clunky but looks, eh.., reasonable maybe, for nawk. If you get no output then you must rule out or find an error message about nawk not found, or if $awkcmd is not assigned you will get a shell error because the shell will try to run the awk code which is gibberish to the shell.
You need to start looking from the very first line, IMO. Keep ruling out problems as you go forward. Do not simply jump ahead 30 lines.

Hi,
I've searched this site and the wider web and have not found anything (that I can understand..) that helps me.

A simple example... (3 Replies)
I want to create an awk script that performs different things on different files.

Hi,
Can someone please guide me how to combine the following two awk calls in one?
I noticed that it is very often situation for me, and I think that it can be replaced with one awk call.
