Not sure how common that use case is. Otherwise, it seems like it would be more noise than actually useful... Also note that bash, when executed as "/bin/sh", still allows syntax that other shells do not necessarily understand. A better test would be to try to run the script with dash or something else that is not bash. -- Marcelo
