1 - Create a *private* GitHub/Bitbucket or similar git repo. Here I assume the repo is:

	https://github.com/calkan/bash_history.git

2 - Create .history directory and initialize it for the repo:

	mkdir $HOME/.history
	cd $HOME/.history
	git init
	touch README.md 
	git add README.md
	git commit -m "first commit"
	git remote add origin https://github.com/calkan/bash_history.git
	git push -u origin master

3 - Make it stop asking for password (no need to worry, still others can't reach it unless they have access to your .history)

	chmod 700 $HOME/.history
	git config credential.helper store
	git push -u origin master

4 - Add the following lines to your $HOME/.bashrc - Michael's crazy BASH trick:

	HOSTNAME="$(hostname)" HOSTNAME_SHORT="${HOSTNAME%%.*}"
	mkdir -p ${HOME}/.history/$(date -u +%Y/%m)
	HISTSIZE=""
	HISTFILESIZE=""
	HISTFILE="${HOME}/.history/$(date -u +%Y/%m/%d.%H.%M.%S)_${HOSTNAME_SHORT}_$$"

5 - Add GitHub support to $HOME/.bashrc below the lines written above:

	touch $HISTFILE
	# add HISTFILE
	git --git-dir $HOME/.history/.git/ --work-tree $HOME/.history/ add $HISTFILE
	# let's be paranoid and save the history frequently. This is to prevent history loss due to drops in network connection
	PROMPT_COMMAND="history -a"

6 - Activate your new environment variables:

	source $HOME/.bashrc

6 - Add the following lines to your $HOME/.bash_logout

	# write history file
	history -a
	# pull it, just in case if you logged out of another session, git will complain:
	git --git-dir $HOME/.history/.git/ --work-tree $HOME/.history/ pull
	# commit & push
	git --git-dir $HOME/.history/.git/ --work-tree $HOME/.history/ commit -am "add $HISTFILE"
	git --git-dir $HOME/.history/.git/ --work-tree $HOME/.history/ push

Logging out takes a second or two while committing to GitHub. It may be a good idea to find a way to disable this for cluster jobs, not sure if .bash_logout is invoked while terminating grid jobs.
