When you write the command name wrong, bash often does this:

septi@norbert:~$ good

No command 'good' found, did you mean:

 Command 'gold' from package 'binutils' (main)

 Command 'gmod' from package 'gmod' (universe)

 Command 'goo' from package 'goo' (universe)

 Command 'god' from package 'god' (universe)

 Command 'geod' from package 'proj-bin' (universe)

 Command 'gord' from package 'scotch' (universe)

good: command not found

Or sometimes it does this:

septi@norbert:~$ nftp

No command 'nftp' found, but there are 23 similar ones

nftp: command not found

Is there any way to ask bash to show these 23 similar commands for me? And, is there a way to show similar commands, including those that aren't yet installed, instead of running the application, ftp for example?
