Here’s a very simple way to type SSH passphrases only once. This simple function, to be added in your ~/.bashrc, will make sure that ssh-agent will always be called before ssh, once per session, so you do not have to type your ssh passphrase more than once:
function sshwithauthsock { if [ ! -S ~/.ssh/ssh_auth_sock ]; then eval `ssh-agent` ln -sf "$SSH_AUTH_SOCK" ~/.ssh/ssh_auth_sock fi export SSH_AUTH_SOCK=~/.ssh/ssh_auth_sock ssh-add -l > /dev/null || ssh-add "$@" } alias ssh='sshwithauthsock ssh' alias scp='sshwithauthsock scp'
