Hi Vishal

Screen has a history command for typed commands.  From the manual:

history

Usually  users  work  with  a shell that allows easy access to previous commands.
For example csh has the command "!!" to repeat the last command executed.  Screen
allows  you to have a primitive way of re-calling "the command that started ...":
You just type the first letter of that command, then hit `C-a {' and screen tries
to  find  a previous line that matches with the `prompt character' to the left of
the cursor. This line is pasted into this window's input queue.  Thus you have  a
crude command history (made up by the visible window and its scrollback buffer).

C-a {,             (history)         Copy and paste a  pre‐
C-a }                                vious (command) line.

It's usually a bit easier to work with your shell's own history feature though.

Hope this helps.
