Ever run a shell script and get the following error? # ./ : bad interpreter: No such file or directory The error may look like there is a problem with your scripts SHEBANG where you specify the interpreter, so you go look and the line contains #!/bin/bash which is correct. So then you start wondering if there is a problem with the /bin/bash binary, and all sorts of thoughts of what would happen if /bin/bash was missing or broken start racing through your head.
