Yes that's the one. It's perfectly fine. I found that if you have to push it past the limit it's probably the wrong tool for the job and it's time to use Python or Perl or pick something off the shelf and think about more structure to whatever you're doing. Shell scripts really don't scale development-wise over time. Definitely agree with the rest of the points though.
