This is a simple problem that I'm sure someone here can solve. I was thinking about making the Roku aliases recommended in an earlier post. These would all be two letters long beginning with 'r'. I wouldn't want the new commands to interfer with anything that already exists, but what's the best way to check? If I go to the command prompt and type r[TAB] I see a list of 174 options for completion, but some are directories and many consist of more than two characters. It looks like "rm" is the only two-character command beginning with "r", but what I want is a simple command that lists all of the two-character commands in my path that begin with "r". How can I get that list? Mike
