ssh-agentでsshのパスワード入力をサボる

一応zsh。.zshrcに以下を追記

.zshrc.linux

# -*- mode: shell-script -*-                                                                                            

echo -n "ssh-agent: "
if [ -e ~/.ssh-agent-info ]; then
    source ~/.ssh-agent-info
fi

ssh-add -l >&/dev/null
if [ $? = 2 ] ; then
    echo -n "ssh-agent: restart...."
    ssh-agent >~/.ssh-agent-info
    source ~/.ssh-agent-info
fi
if ssh-add -l >&/dev/null ; then
    echo "ssh-agent: Identity is already stored."
else
    ssh-add
fi
