I once had an insanely important job interview where I pronounced “fstab” as “F Stab” not “FS Tab.”
I still don’t know what “-tab” is about, but it’s used a lot in /etc. Maybe because the file formats use \t as separators?
At $PREVIOUSJOB I worked with a guy from Boston who pronounced "query" as "quarry". But he had a lot of bizarre pronunciations, so we just let it go. And not just because Boston, either.
I can still recall, with Proustian clarity, my feelings upon learning 'cat' and, simultaneously, that it stood for 'concatenate': "but surely in 99% of cases you are 'catting' a single file, so that name makes no sense". Was I wrong? I was not.
