I can't recall the software, but few years ago there was a famous typo in the update script, namely a space after '/usr' in the rm -fr command which effectively removed whole /usr. Does anybody remember what that was?

There so many comments on that commit that Microsoft Github's backend apparently cannot load the page -- I just get the "unicorn".
Anyway, this issue also points it out: https://github.com/MrMEEE/bumblebee-Old-and-abbandoned/issue...
rm -rf "$STEAMROOT/"*
and if $STEAMROOT wasn't set, that amounted to rm -rf * rm -rf "${STEAMROOT:?}/"*
Will exit with error instead of running rm if STEAMROOT is unset. Even if used inside a conditional.
