What history are you talking about? bash already stores command history, I think that the number of commands remembered is configurable.

Yes. The history of commands executed for the users will be stored in the .bash_history file inside the home directory. Also the number of commands to be stored in history can be configured using the H!ISTSIZE property. Some additional useful commands can be found on website.

Hello dhoruboyina manjunath,

Welcome to CodeRanch!

As above posts mention, command history is already store in shell's history file (e.g. ~/.bash_history in case of bash).

Also, since this file is in home directory, there will be separate history file per user.

I hope this helps.
