minus-square@[email protected]linkfedilink2•8 months agoset -euo pipefail at the top of every script makes stuff a lot safer. Explanation here.
minus-square@[email protected]linkfedilink0•8 months 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!
