The only thing that separates tactical from strategic in an enterprise setting is time.

Due to my frustrations with various constraints with running things in parallel (and my complete ignorance of GNU parallel), I wrote a script that does similar work in Perl (with some added custom features we needed). Against all my expectations, 16 years later, that script is still being used (unmodified).

Indeed.

Parallel was created 2002-01-06: https://www.gnu.org/software/parallel/20th-birthday.html

It did, however, only become a GNU tool in 2011, so I think it is completely fair that you were ignorant about it 16 years ago.

Ah that is interesting - yeah, we were on Sun Solaris at that time (which AFAIK remember, didn't have the GNU toolkit on it). Thanks for making me feel better about it :)
