How to change Bash History Size on Mac OS X

Guys, I hope you must be aware, that the commands that you type in terminal get saved in the history. On Mac OS X, the default size of commands history is 500 i.e it saves the most recent 500 commands that you typed in terminal in a special file named "bash_history".

Open Terminal and check for yourself.

vi ~/.bash_history

Hit escape and type this to see the history limit
:set number

Now to change this default limit of 500 to something else, lets do the following in Terminal.

sudo vi ~/.bash_profile

Enter your password.

Add this line to the file :

#history

HISTFILESIZE=1000

That's it. It means from now on, it will save upto 1000 latest commands that you typed in history. Ciao!
