【Linux】find & grep 併用コマンド

Posted at

ソースの中から文字列「hogehoge」を検索するには

find . -name \*.c -exec grep hogehoge {} \;

とすればよいが、これでは *.c のファイルの数だけ grep コマンドが実行され、時間がかかる。そういう場合は

find . -name \*.c -print | xargs grep hogehoge

とすればよい。もっときっちりやるなら

find . -name \*.c -print0 | xargs -0 grep hogehoge /dev/null
find . -type f -exec grep -il confirm {} \;
