Shellcheck is immensely helpful and I highly recommend incorporating it into your editing workflow (that is, lint as you go with a language server) before it hits the CI/CD pipeline. (ba)sh scripting has so many footguns it astounds me that so much complicated code has been written (more-or-less) successfully in it. Once I reach more than a few dozen lines I usually hit the escape hatch and reach for a more powerful scripting language (you can always still shell out to utilize handy CLI tools if you need them).
