ssh-agent for Windows Contrary to most scripts available on the web, this one allows to use the same ssh-agent for all shell sessions. It works by specifiying an explicit socket '/tmp/ssh-agent' and using 'ps' to retrieve the pid.

ssh-agent.sh

function init_ssh_agent {
  echo "Initializing new SSH agent..."
  rm -f /tmp/ssh-agent
  eval `ssh-agent -a /tmp/ssh-agent`
}

function setup_existing_ssh_agent {
  echo "Using existing SSH agent..."
  export SSH_AUTH_SOCK=/tmp/ssh-agent
  export SSH_AGENT_PID=$(ps -s -u $USERNAME | grep ssh-agent | cut -d' ' -f4)
}

if [[ -n $(ps -f -u $USERNAME | grep ssh-agent) ]]; then
  setup_existing_ssh_agent
else
  init_ssh_agent
fi
