Sorry to double post but I remembered another nice tool (or rather shell).
As a shell give fish a try, it is VERY similar to bash but has a nice feature that actually color codes the command line as you type to indicate commands and files that are found or not.
As you are typing the word you are on will change from red to green if the command/file is found or not. It also does an underline to indicate files found. When using tab completion the whole line will flash another color if there is nothing found to complete the line.
Just wanted to add that as an option as well.
