Git：git grepコマンドでマッチしたファイル名のみを表示する方法

git grepコマンドでマッチしたファイル名のみを表示する方法

git grepコマンドでマッチしたファイル名のみを表示するには-lオプションを指定します。

オプションの説明

 -l, --files-with-matches, --name-only, -L, --files-without-match
     Instead of showing every matched line, show only the names of files that contain (or do not contain) matches. For better compatibility with git diff,
     --name-only is a synonym for --files-with-matches.

-lオプションを指定した場合

$ git grep -l time_t | head
