How to get bash history of already running session?

1.) I was thrown out of my server because of a cable fault.
2.) I logged in again using a new session. History of the other session is not accessible.
2.) I want the bash history from the other session.

Any ideas if this can be accomplished? (I know of methods how to change this for the future)


If you send SIGHUP or SIGTERM to your previous bash session, it should terminate and write out its history. Once that's done, start a new bash session (or just look in your ~/.bash_history file) to access the command history.

So in summary, use something like ps -fu <your_username> | grep bash to find the PID of your previous bash session, then kill <bash_pid>.
