Linuxのcrontabを使用してPythonスクリプトを実行しようとしています。このスクリプトを10分ごとに実行したいと思います。
私はたくさんの解決策を見つけましたが、どれもうまくいきません。例:/etc/cron.dでanacronを編集するか、を使用しますcrontab -e
。この行をファイルの最後に置きましたが、何も変更されていません。サービスを再起動する必要がありますか?
*/2 * * * * /usr/bin/python /home/souza/Documets/Listener/listener.py
これを構成するには、どのファイルを編集する必要がありますか?
前もって感謝します
これがスクリプトです。
