minus-square@UnityDevice@startrek.websitelinkfedilink27•1 year agoset -euo pipefail at the top of every script makes stuff a lot safer. Explanation here.
minus-square@deadbeef79000@lemmy.nzlinkfedilink8•1 year agoYep! I always do this too. TL;DR: e aborts the whole script on a non-zero error. u aborts when using an undefined variable. -o pipefail aborts a piped compound command when one of the piped commands fail. Any other way lies madness. Or erasing the whole filesystem apparently!
