GitHub Gist:Linux コンソールのカーソルの形、色、点滅速度を変更する方法
.bashrc で次のカーソル書式設定を定義します ファイル (または /etc/bashrc ):

ほとんどのアプリは、cnorm 機能を使用して、カーソルを「通常の」状態に戻します。デフォルトでは、これは点滅する下線です。ただし、terminfo でこれをオーバーライドできます。これにより、ほとんどのアプリケーション (vim、tmux など) が修正されます。これらのコマンドを発行します:
infocmp -A /usr/share/terminfo linux > linux
patch -lp1 <<EOF

必要に応じて上記のパッチを変更します。これにより、~/.terminfo/l/linux が作成され、ほとんどの端末アプリで取得されます。
bash を使用する場合、各コマンドの後にコマンドを実行する PROMPT_COMMAND を使用できます。以下を .bashrc に入れます
PROMPT_COMMAND='echo -e "\e[?16;0;200c"'
