$PATH変数をデフォルトのKali設定にリセット

Kali Linuxローリングディストリビューションを実行します。

次の構文を使用して、Cuda Toolkitを/opt/ディレクトリにインストールしてみてください。

chmod +x cudatoolkit_4.1.28_linux_64_ubuntu11.04.run
./cudatoolkit_4.1.28_linux_64_ubuntu11.04.runConfigure  

echo PATH=$PATH:/opt/cuda/bin >> ~/.bashrc
echo LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/cuda/lib >> ~/.bashrc
echo export PATH >> ~/.bashrc
echo export LD_LIBRARY_PATH >> ~/.bashrc

端末を開くたびに、上部に次のように表示されます。

bash: /opt/cuda/bin: そのファイルやディレクトリはありません。

bash: /opt/cuda/bin: そのファイルやディレクトリはありません。

bash: /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin: そのファイルやディレクトリはありません。

bash: /usr/local/sbin: ディレクトリです。

ターミナルを起動するたびに表示される「bashメッセージ」を削除できるように、デフォルトのKali Linux設定に戻る必要があります。
