This is one of many ways to do it...
By saying this is one of many, I mean it - here is an example of a one-liner that will do nearly the same thing without the error handling or variables: As you can see, the "grep" command is the same as in the script, but the messages are handled differently. The commands after the "&&" will execute if the previous command was successful, and the command after the "||" will execute if it was not successful.
