git statusコマンドでIgnored files（無視ファイル）を表示する方法
git statusコマンドでIgnored files（無視ファイル）を表示するには--ignoredオプションを指定します。
オプションの説明
--ignored[=]
Show ignored files as well.
The mode parameter is used to specify the handling of ignored files. It is optional: it defaults to traditional.
The possible options are:
• traditional - Shows ignored files and directories, unless --untracked-files=all is specified, in which case individual files in ignored directories
are displayed.
• no - Show no ignored files.
• matching - Shows ignored files and directories matching an ignore pattern.
When matching mode is specified, paths that explicitly match an ignored pattern are shown. If a directory matches an ignore pattern, then it is shown,
but not paths contained in the ignored directory. If a directory does not match an ignore pattern, but all contents are ignored, then the directory is
not shown, but all contents are shown.
