Installation

1. mkdir -p ~/.config && touch ~/.config/ssh-agent.pid
2. Paste the contents of ssh-agent-manage.sh into your .bashrc or .bash_profile or similar
3. killall -9 ssh-agent
4. Start a new terminal session (note: old sessions will not see ssh-agent, only new ones)

Details

This snippet, when included in .bashrc, will ensure that your session has a working ssh-agent with all your ssh keys loaded into it. It does this without creating separate ssh-agent processes by:
