個人的に便利だったdiffの使い方

Last updated at Posted at 2012-06-27

symfonyの開発環境のconfigを結構いじって、configureもした状態でコミットする際、差分を見るのに困っていたら教わった便利なdiffの使い方。

dev.foo/ が開発環境
prod.foo/ が本番と同様の環境を構築している

新規で追加されたファイルのみを抽出

diff -r dev.foo/ prod.foo/ | grep "^dev.foo"

差分のあるファイルのみを抽出

diff -r dev.foo/ prod.foo/ | grep "^diff"
