gitで使っちゃいけないコマンドを.bashrcで設定する

More than 5 years have passed since last update.

以下の関数を.bashrcに追加します。

function git() {
    CMD=$1
    CURRENT_DIR=`pwd -P`
    if [ "${CMD}" == "clean" ]; then
        # gitで管理してないデータなどがあるリポジトリで実行すると大変なことになるので禁止する
        echo "You must not use \"git clean\"."
    elif [ "${CURRENT_DIR}" == "${HOME}/workspace/tools" -o "${CURRENT_DIR}" == "${HOME}/workspace/docs" ] && [ "$CMD" == "push" ] ; then
        # 実験的に変更しているファイルのあるディレクトリではpushしない
        echo "You must not use \"git push\" here."
    else
        command git "$@"
    fi
}

command コマンドはエイリアスや関数以外のコマンドを実行するコマンドです。
