just update the remote origin with this command

Typing a big command on Terminal ?

Why don't you try reverse-i-search  feature built in the terminal. Just press Ctrl + R and only a unique part of the big command that you have already executed before.

Here is how I start eclipse on my system just by typing 'ec'

You might find a problem associated with reverse search that it just searches in the reverse direction and once your are past what you were searching for , your efforts are rendered useless.

There is a solution around this and you can enable forward search by some modifications.

• Open up .bashrc and add the following lines in it 
• stty -ixon
• refresh the bash setting by executing
• source .bashrc

Now you will be able to search forward using Ctrl + s .
