Initialize ssh-agent in .bashrc

.bashrc_ssh

# Set up ssh-agent
SSH_ENV="$HOME/.ssh/environment"

function start_agent {
    echo "Initializing new SSH agent..."
    /usr/bin/ssh-agent | sed 's/^echo/#echo/' > "${SSH_ENV}"
    echo succeeded
    chmod 600 "${SSH_ENV}"
    . "${SSH_ENV}" > /dev/null
    /usr/bin/ssh-add;
}

# Source SSH settings, if applicable
if [ -f "${SSH_ENV}" ]; then
    . "${SSH_ENV}" > /dev/null
    #ps ${SSH_AGENT_PID} doesn't work under cywgin
    ps -ef | grep ${SSH_AGENT_PID} | grep ssh-agent$ > /dev/null || {
        start_agent;
    }
else
    start_agent;
fi

I've made a few changes in my fork of this gist:

• Less output
• A safer way to create ~/.ssh/environment
• A more readable way of checking whether ssh-agent is running.
