我的 bash 脚本在由 crontab 触发时不起作用，但当我手动触发它时可以工作？

这是 cron 条目

*/1 * * * * ./home/usr/automation/check_rejected_files.sh > /home/usr/automation/cronout

它生成了文件但没有其他事情发生，我在脚本的开头添加了一个日期日志，这样我就可以看到脚本是否运行，并且当它通过 cron 触发时不会发生任何日志记录，感谢您的帮助，谢谢

crontab像这样删除条目中的点：

*/1 * * * * /home/usr/automation/check_rejected_files.sh > /home/usr/automation/cronout
