Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Check command history, but avoid running it

!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.

Comment by pkkid 302 weeks and 2 days ago

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

!whatever:p

did you?

Comment by p3k 302 weeks and 2 days ago

Works on Opensuse 11, very cool!

Comment by Williebee 302 weeks ago

looklike it works, but may be batter to cat .bash_history?

or I`d just not understand the true meaning of this thing

Comment by GreyCardinal 301 weeks and 6 days ago

Oh! understood!

ubuntu 8.10 -works

debian etch - no -:(

Comment by GreyCardinal 301 weeks and 5 days ago

@p3k

hahah.... thanks.

Still i prefer control + r

Comment by cowholio4 300 weeks and 6 days ago

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

Comment by Buzzcp 292 weeks and 6 days ago

ctrl+r works better and everywhere.

Comment by oringo 289 weeks and 6 days ago

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

Comment by akg240 272 weeks and 4 days ago

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.

Comment by magikid 254 weeks and 3 days ago

Agree with C-r

Comment by Erus 245 weeks and 3 days ago

use bash lusers! pkkid is right!

Comment by buzzy 238 weeks and 5 days ago

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.

Comment by Chartreuse 237 weeks ago

function hg(){ history | grep $1; }

Then "hg command" will print all previous commands

Comment by quincymd 232 weeks and 5 days ago

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!
