Bash(Viモード)の設定やコマンドのメモ
先日、BashをViモードに変更して快適になった話というブログを書きました。
BashをViモードに変更して使うようになってから、快適にターミナルを使っています。
ただ、前の記事では、Viモード時のコマンドについて、全く書いてなかった…
ということで、色々と調べたので、参考になったURLを紹介します
ググり続ける日々
色々なキーワードでググりまして、よい情報があったので、以下にURLを記録しておきます

- The Definitive Guide to Bash Command Line History
- Calmar on ‘Vi Keybindings in Bash’
現在の設定を確認する
以下のコマンドで確認できます
bind -p
出力を見ると、色々と設定されているのが分かります
私は.inputrcに"\C-l": clear-screenを設定しているため、反映されています
しかし、設定をコメントアウトするとclear-screen (not bound)となります
また、コマンドモードに切り替えるキーにControl-jを設定していますが、以下の出力から分かるように、デフォルトのキー(Esc)もあるので、色々なキーで設定しても問題ないようです
ということで、キーと任意の値を設定すれば、よさそうです
