Actually, it would be good if someone with a good deal of bash
scripting experience chimed in.

eval is not safe to use in a bash script. If the input is crafted
cleverly, the script can execute unwanted commands. Not to mention the
above examples don't work great with characters like "!" which are
evaluated as the built-in history command by eval. You need to
actually escape my example with backslashes for that reason.
