Git Bash for Windows script for SSH Agent and Keys management

.bashrc

# REQUIREMENTS
# 1) Understanding that this script is provided as-is and I have no responsibility for whatever damage occurs
#    That said, if the script was strictly tested and no problems should arise if you use it without any modifications
#	of areas which not states that can be modified
#    Also if you find any problems let me know to see if I can help you (and/or fix the script)

# Put this at the end of your ~/.bashrc if you already have one or just throw it in your home directory if you don't
# Make sure there are no other scripts starting ssh-agents or adding keys

# This assumes you have https://github.com/magicmonty/bash-git-prompt in your home directory
# If it's in another directory just change the "source $DIRECTORY" line accordingly
# Enable only on git repositories
GIT_PROMPT_ONLY_IN_REPO=1
# Source the gitprompt file
source ~/bash-git-prompt/gitprompt.sh

# Check if there's any running instance of ssh-agent for the current user
if ! ps -u $(whoami) | grep 'ssh-agent' | grep -oE '^\s*\S*' > /dev/null; then
	# If no instance is found
	
	# Start ssh-agent and dump output to .ssh-agent-thing
	ssh-agent > ~/.ssh-agent-thing
	
	# Eval the dumped agent for the current bash
	eval "$(<~/.ssh-agent-thing)"
	
	# Add the keys from ~/.ssh ending with .key since the ssh-agent was just started
	ssh-add $HOME/.ssh/*.key

# If there's a running instance check if it was already evaled for the current bash
elif [[ "$SSH_AGENT_PID" == "" ]]; then
	# If no ssh-agent was evaled
	
	# Eval the existing ssh-agent instance for the current bash
	eval "$(<~/.ssh-agent-thing)"
fi

Known Issues:

• If you just exit the script with "CTRL+c" or similar without providing the passwords for one or more keys those keys will not be added and will not be prompted to the next time you open the terminal unless you manually kill the running SSH Agent. You can use ssh-add to add those keys without any issue.
