Check command history, but avoid running it

!whatever:p
!whatever will search your command history and execute the first command that matches 'whatever'. If you don't feel safe doing this put :p on the end to print without executing. Recommended when running as superuser.

Pressing +r then start typing the command will show you live updates of the history as you type. You can also use the up and down arrows to find the one your looking for.

@cowholio4: i got it working with both ubuntu and os x; you did not actually type in !whatever:p did you?

looklike it works, but may be batter to cat .bash_history? or I`d just not understand the true meaning of this thing

I can only think that the :p means "just kidding about re-executing it" :)

ctrl+r works better and everywhere.

... or you could just set histverify ("shopt -s histverify") and be done.

On ubuntu also: history|grep whatever That will show every time in your history file the command has been called rather than just the last time.

To those who say Ctrl-R works everwhere, try running Ctrl-R on csh/tcsh, or ksh, Ctrl-R only works on bash and Z shell. While !search:p works on many more, also it is more continent to type a simple command in than to use a shell feature, as you can use it in a string of commands.

function hg(){ history | grep $1; } Then "hg command" will print all previous commands

it works fine like this: 1. type echo hello then you have it in your history. now you can type: !echo and you get "echo hello" in your commandline with the cursor at the end, so you can edit it before you commit it or you press ^C to cancel very useful!
