Sometimes we need to enter same command multiple times by changing 1 or 2 arguments. This is very tedious job to do. Update and execute command every single time!
But worry not as what you are going to see in next few minutes will act as a big time savior in such cases.
If you use shell in default mode (
emacs if you don't know :P), you can press
ctrl-e and enter text editor to edit all the commands together by using features of your editor like copy, paste visually select etc. Save and exit editor to execute all the commands.
If you are using
vi mode, you can move to normal mode by pressing
Esc and then pressing
v would achieve similar functionality.
You can switch between
emacs mode by commands
set -o vi and
set -o emacs respectively. Your keybindings will work according to your mode.

As suggested by Tai Kedzierski here, you can choose the editor in which you want to edit commands by setting environment variable
It's a good idea to set them in
$HOME/.profile. Former one will set it for every bash instance and latter one will set it globally which will be done at time of system startup. I prefer latter one.
