Search command history on bash

ctrl + r
Very handy and time-saving. Do a 'ctrl+ r' on command prompt. You will see a "(reverse-i-search)`':" mark. Just type any sub-string of the command you want to search(provided you have used it sometime in the same session). Keep on searching by repeatedly pressing ctrl+r. Press enter once you get the desired command string.
Sample Output
blue] $
(reverse-i-search)`': ls

#Press enter to run the selected command.

Great! Very useful

Personally, I prefer bash's "history-search-backward" function, which takes what you've already typed and searches backwards. This is also the way tcsh's esc-p history search works. I am usually in the middle of typing a command when I want to search for it. Using ctrl-r requires you to erase what you've already typed before typing it again after doing the ctrl-r.

Instead of erasing what you are typing to do the Ctrl-R, you can do a Ctrl-C. It will put you back to the beginning of a command line but leaves the command you just wrote on the line above. Lets you copy from that command.

Any thoughts on this command? Does it work on your machine? Can you do the same thing with only 14 characters?
