鍵の配置とGit Configの設定

ssh -t でbash起動するからそこで毎回コマンドコピペしてやる

  cat ~/.ssh/isucon12-qualify | ssh $h -t 'cat > .ssh/isucon12-qualify; chmod 600 .ssh/isucon12-qualify;  /bin/bash -l'
done

cat >> ~/.ssh/config << EOF
Host github github.com
  HostName github.com
  IdentityFile ~/.ssh/isucon12-qualify
  User git
EOF
git config --global user.email "yamachu-isucon12-qualify@example.com"
git config --global user.name "yamachu-isucon"
sudo vi /etc/hostname
