Another approach to working with "awk"
A reader writes in with the following note:
I've just picked up your book Wicked Cool Shell Scripts, and there are a lot of nifty things in it. I too have accumulated a lot of things generally in small scripts or more frequently in bourne/bash functions. I was particularly tickled to see a lot of very similar code, one such that jumped out at me was your gmk function in one script (I called mine kmg).
You're right, this is a better approach to the problem, but you're not solving the same problem I am. :-)
What I'm getting is the last field if and only if it's prefaced by a space, whereas you're ignoring the leading space and looking just to see if the last field matches "$1".
Where might this differ?
When the output is a single word on a line by itself: with your conditional it could match, whereas with mine it couldn't.
Nonetheless, I am happy to hear about smarter and more logical ways to solve problems that I talk about in my book, so please do feel free to send any further thoughts in!
