Re: CCIE Lab Tips: Housekeeping Commands

To add:
I think adding aliases is for suckers. If you're constantly in your
own environment, I can understand. I can be convinced there.

Otherwise, learning the shortcuts for all the commands I think is the
way to go. I cringe just a little bit every time I see someone type
out 'include' instead of i, 'exclude' instead of 'e', 'begin' instead
of 'b', do a 'show run' to troubleshoot something. If you become
intimately familiar with where you want to look at in the
configuration and use the pipe commands, and learn the shortest letter
combinations for all your commonly used commands, I think you'll find
better success because you won't have to enter aliases all over the
place.

Although I still install one one nexus switches for 'wr' because copy
run start is a dumb command.

If you're administering devices without logging sync, you just don't
know better. I don't know of a single reason not to have this
everywhere (except NXOS where I haven't found an equivalent).

The only commands I disagree with (for lab) - transport input none,
alias commands, and the ntp commands.
