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
Sample Output
$ history | grep 'ipt'
  2    iptables -L -n -v -t nat
$ !2     # will execute the iptables command

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.
