Rewrite this script to make it easier to read and disable full-text scan when the executable is not even a text 1. Check if the file is a script and is executable and lack of shebang.(If not executable, we should not let it run.) 1.1 If python, then use python, else use bash. 2. If do not need to fix,just try to run.
