It's dangerous when `cd` fails but following commands keeps running
which would lead to expected results.

For those shell scripts without `set -e`, use `exit 1` before furthur
refactor could be a safe and efficient workaround, for thoes shell
scripts with `-e`, the shell(script) will exit immediately if any
command has a non-zero exit status, so they don't need `exit 1`
