Vimの設定ファイル.vircと.vimrc

# .vimrcが機能しない

vimのカスタマイズをする時に.vimrcを編集せよという記事がありますが、実際に.vimrcで設定するとうまく機能しない事があります。

この場合は.vimrcではなく.vircとなっている可能性があります。
特にAlmalinuxを標準インストールした時は.vircとなっています。

これは`vi --version`または`vim --version`コマンドを実行する事で確認する事ができます。

```bash
$ vi --version

```

`vimrc file`で指定されているのが正しい設定ファイルになるので、それに合わせる事で機能します。
