Ok, going for full controversy here.
zsh = "zoosh"
ssh = "shoosh"
sudo = sue-dough
Before you achktually me, I know it's supposed to be "sue-DO", because the acronym stands for "superuser do", but for the life of me, when I see those letters together it just seems wrong to pronounce it that way.
It’s “zed” because Brits know that it came from “zeta,” which has no “d” in it. That’s also why they don’t say “ay bee see dee eee eff jee”, they say “al bed cam del epp dye gam.”
