Here is a version of that awk script wrapped in a Korn shell script that adds command line options to specify the number of matches for each ERE, a simplified case insensitive ERE option, an option to name an alternative pathname to the file containing your EREs, and an option to print some debugging information while the awk script is running:
Although written and tested using a Korn shell, it should work with any POSIX conforming shell. The limitations on the case insensitive ERE processing are detailed in the comments in the awk script.
Does this help?
