    that was just a poor example.. You can see geirha's example. (@geirha's thanks,been dormant for a while and forgot about FILENAME). Sorry what point are you proving again?

    bash/sed/awk are all worth learning.
    when it comes to parsing files, bash (to call awk ) and awk is all you need. The rest of the tools that can read files -> wc, tr, sed, grep, cat, nl, head, etc one can chuck it in his toolbox and never use it. But for some, like tail, is sometimes indispensable due to its purpose. (although you can also use awk to simulate "tail")

    If awk is a programming language, what is it designed to program? can it program an entire program, with a gui and such?

    Have you read the link "Effective awk" in my sig? awk is little language that provides you with the basics for programming, arrays, variables, functions, if/else, switch etc. What can it program ? anything that you can produce with those programming features! Except GUI...because it doesn't have that kind of library (not like fully featured ones like Python or Ruby). See here for more on what awk can do
