To avoid this, make sure you handle the cases when `cd` fails. Ways to do this include
* `cd foo || exit` as suggested to just abort immediately
* `cd foo || exit` as suggested to abort immediately, reusing exit code from failed `cd` command
* `cd foo || { echo "Failure"; exit 1; }` abort with custom message
* `if cd foo; then echo "Ok"; else echo "Fail"; fi` for custom handling
* `<(cd foo && cmd)` as an alternative to `<(cd foo || exit; cmd)` in `<(..)`, `$(..)` or `( )`
