I see

I'm now considering doing it in the way you suggested, but I have another question about your suggested method.

My problem: Originally I ran something like ls -al | grep Jun 22 | cut -c49-100 >> myLs.txt to give me just the time and filename of all files for June 22nd in a text file.

With that text file I began awking.

You're suggesting that instead of using while read hour file that I begin the awk right away, to avoid repeating all that code that I did.

Since the text file with the LS holds the filenames of CSV files, I need to be able to, at some point, awk those files to perform some count calculations. I don't think I could use a nested awk.. awk within an awk to open those files found in the first awk. (or could I?).

I'll pick up the book over the weekend, thanks.

rules are there but asking 2 questions out of 30 is surely understanable esp when the instructor gives an open book test and urged us to seek answers anywhere we can except from him directly.

OPTIONS

       See gawk(1) for a full description of the AWK language and the options that gawk supports.

EXAMPLES

       cat << EOF > test.awk
       @include getopt.awk

       BEGIN {
	    while (getopt(ARGC, ARGV, "am:q") != -1)
