ssh-find-agent is a tool for locating existing ssh compatible agent processes (e.g., ssh-agent, gpg-agent, gnome-keyring, osx-keychain); and, optionally, setting SSH_AUTH_SOCK accordingly.

Somewhere in shell initialization (~/.bashrc or ~./.zshrc)

source ssh-find-agent.sh # for bash
emulate ksh -c "source ssh-find-agent.sh" # for zsh

Add the following to automatically choose the first agent

ssh-add -l >&/dev/null || ssh-find-agent -a || eval $(ssh-agent) > /dev/null

To choose the agent manually run

ssh-find-agent -c

NOTE: The choose option is Useful when you actually want multiple agents forwarded. E.g., while pairing.

To list the agents run

ssh-find-agent -l

This will return a list of export commands that can be used to set the socket.

Should this output be executed it will set the socket to the last agent found.

eval $(ssh-find-agent -l)
