Good on you.
It's funny how infinite is the ocean of command line utilities, e.g. as a
long time user of the command line:
1. I only learned about "grep -r" 8 years ago (in my first workplace in
2. I only discovered that "less -R" (capital "R") is much better for
viewing and searching colorised text files than "less -r" (lower case "r")
a couple of weeks ago.
3. two days ago I found how to make "awk" access environment variables
(through ENVIRON["VARIABLENAME"]), though I knew what I was looking for.
4. Only a short while ago I learned a trick to script "echo line >>
root-only-writable-file" by replacing it with "echo line | sudo tee -a
And the list goes on and on.
The take away? Command line veterans can also benefit and enjoy such a
meeting by learning and sharing their own knowledge. Wish I could attend.
