-bash: gawk: command not found

You might be able to get away with just 'awk'. This AWK installed by Apple is presumably a Berkeley Unix version derived from the original Bell Labs AWK, installed under its original command name of awk(1) - gawk(1) was a name used to prevent a GNU Awk from clashing with an installation of the original.

I can't remember just how compatible the original awk(1) is with gawk(1). If you really do want features added by the latter, you will have to install it from http://gawk.darwinports.com/

AWK is a nice little report generation language and interpreter. Many prefer the more-general programming language Perl these days (it was partially inspired by Awk) which has a far more comprehensive library, but I still use Awk (often in a pipeline with sort(1) etc) from force of habit when I need to perform a small data-processing task.

I tried AWK and it works. Thanks.

But I still want to try gawk. So I installed from http://gawk.darwinports.com. I have downloaded gawk-3.1.6 and it is now in the application folder. But still received message "gawk : command not found". Is it because it is not in the correct path.
