#Poll: Curious about people's attitudes towards shell scripting.

Two part question:

1. Are you a DEVeloper (or working in a development-heavy role), OTHER-IT worker (such as a sysadmin, architect, anything in a non-development-heavy role), or NON-IT (accountant, doctor, whatever)
2. Do you HATE shell scripting, are you INDIFferent towards (or ignorant of) shell scripting, or do you LOVE it?

I've probably tooted about this before, but I don't know why this isn't standard.

It's just so obvious, at least to me. ;)

Process Substitution is hella neat.

$ diff important-data.txt <(clipo |sort -u)

(Of course #mksh has it as well ;)

While we could add a bunch of CHECK_PORTABILITY_SKIP entries to skip these files, I prefer to fix things properly, and so have committed a general fix for this which should speed up most packages.

https://github.com/TritonDataCenter/pkgsrc/commit/df1af49c2953c235c8af501a53f13cdfa5bbf91c

Nice reduction in runtime from 86 seconds down to just 1!

If anyone has access to really old systems and are able to tell me if they do not have "read -n" then that'd be hugely appreciated, though it's likely we'd bootstrap #mksh on them anyway.

Interesting performance and behaviour difference between shells and the "read" builtin.

After upgrading to macOS Sonoma I noticed the #pkgsrc check-portability script occasionally taking over an hour and falling foul of my "ulimit -t 3600".
