Scripts to keep track of bash history in *nix forever and recover from crashes of .bash_history

I like to keep track of the commands I executed in bash forever. This involves two things: (i) Updating .profile/.bashrc to request history storage forever (ii) Taking steps to ensure that we can restory history even if a crash occurs

(i) Update .profile/.bashrc to store history forever:

In order to store commands from all different instances of the terminal in the history file. Or also known as - to keep command history from multiple bash sessions.

shopt -s histappend

To ask for a heck of a lot of history to be stored.

export HISTSIZE=100000 export HISTFILESIZE=1000000

(ii) Taking steps to ensure that we can restory history even if a crash occurs

(a) Create a cron job to backup history periodically

I have a simple Python script to copy .bash_history: python make_history_bkup.py
Include the following line in crontab: 5 * * * * python /home/ramapad/make_history_bkup.py

(b) A script to restore history after a crash:

I wrote a script that will use the backups created by the cron jobs to stitch together the history file from all the backups: python fix_history.py .bash_history_consolidated

ramapad/bash_history_stuff
