The clean / portable way is in my experience always simpler, or rather, more rudimentary than using unnecessary GNU/Linux-only commands and constructs, simply because the clean / portable methodology uses the lowest common denominator. If you know of, or have such a case, I would be really interested to see it, out of purely professional interest. Nobody wants to debug shell scripts. I want to debug shell scripts, because of all the debugging I've done over the years, shell script debugging is by far the quickest / easiest: DEBUG="${DEBUG:-false}" $DEBUG && set -x and one can see the machine state immediately. Best debugging experience by far.
