#For Previous Command (for comparison)
!-1     repeat whole command
!!      repeat (shortcut)
!:0     command
!^      first parameter
!:1     first parameter
!:1-4   first 4 parameters
!$      last parameter
!*      all parameters
!!:s/bash/zsh (or ^bash^zsh)
!^:t    just file name of first parameter
!$:h    just path of last parameter
!-2$:r  just file name without extension of first parameter

For last but one command
!-2     repeat last but one command
!-2^    first parameter last but one command
!-2$    last parameter last but one command
!-2:2   second parameter of second but last command
!-2:s/bash/zsh substitute bash by zsh in the last but one command


Most of them are applicable for bash as well.

I recently moved to using zsh instead of bash. (So, you may expect more of my zsh-related posts). Something that bugged me since the beginning is that when I try to see all the commands used previously using history command, zsh does not list all of them! The correct way to get the desired behavior is to use
$ history 1
in the command line, which literally means start listing from the 1st command in the history file.

Since we are at it, I though it would be nice to post a nice history related function:

h() { if [ -z "$*" ]; then history 1; else history 1 | egrep "$@"; fi; }

If you type
$ h ls
it’ll give you all the history related to the command ls. If it does not follow an argument, then the function just shows normal behavior of “history 1” mentioned above.
