Search command history on bash

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.

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.
