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.

Execute the command given by history event number

You can find a command's history event number via the `history` command.

You can also put the history event number in your prompt: \! for bash, or %h for zsh.

Finally, I would like to point out that by "number", I mean POSITIVE INTEGER. Not, say, a letter, such as 'm'. Examples:

!1

or

!975

Know a better way?

If you can do better, submit your command here.

What others think

Actually, this will only execute the most recent executed, so where does the "number" come into play?

2997 mail -s test jj

2998 exit

2999 history

!m will execute 2997

Did you even read the description? !! returns the previous command.

zsh

% PROMPT='%h %% ' 1012 % echo "This is history event number 1012" This is history event number 1012 1013 % history | tail -n 2 1011 PROMPT='%h %% ' 1012 echo "This is history event number 1012" 1014 % !1012 echo "This is history event number 1012" This is history event number 1012 1015 %

bash

history | tail -n 2 1003 echo "This is history event 1003" 1004 history | tail -n 2 !1003 echo "This is history event 1003" This is history event 1003

Other resources that confirm my command is correct:

http://www.talug.org/events/20030709/cmdline_history.html

http://www.catonmat.net/blog/the-definitive-guide-to-bash-command-line-history/

I recommend against down-voting a command unless you know what you're talking about.

Also, 'm' is not a number.
