I love ssh-agent, but always found that running source ~/.ssh.agent annoyed me!

That was before I wrote this code, which I absolutely love:

source ~/.ssh.agent

PID=$SSH_AGENT_PID
if [ -f /proc/$SSH_AGENT_PID/cmdline ]; then
        CMD=`cat /proc/$SSH_AGENT_PID/cmdline`;
        if [ "$CMD" != "ssh-agent" ] ; then
                PID=0
        fi
else
        PID=0
fi;

if [ "$PID" -eq 0 ]; then
        ssh-agent > ~/.ssh.agent
        source ~/.ssh.agent
        ssh-add
fi;

Put simply, when added to your .bash_profile this code will ensure that your current ssh-agent is loaded. You may now ssh freely into servers without always typing that 100 character SSH Key password 🙂
