indibm202 22: !!
date

indibm202 23:

What is the alias for the second most previous command?

Answer 1

If tcsh is anything like csh (and I think it is), you should be able to just use:

!-2

to execute the second-to-last command (!! is shorthand for !-1).

Alternatively, you could use history to check out your last few commands and then use:

!N

where N is the command number for the command you want to re-execute.
