执行 r 脚本的 cron 作业不起作用 [英] cron job to execute r script not working

问题描述

我是 cron 的新手.我想使用 cron 定期执行 r 脚本.我刚刚将作业添加到 crontab 以检查它是否有效.但不幸的是，没有任何效果.我编写了一个测试脚本，并在 cron 作业中每 5 分钟安排一次.

I am new to cron. I want to execute r script on regular basis using cron. I just added the job to crontab to check if it is working. But unfortunately, nothing is working. I wrote a test script and scheduled it for every 5 mins in cron job.

这是测试 R 脚本:

print('HI')

定时任务:5 * * * * sudo Rscript/path/to/script/test.R

但是当我从终端执行它时，它工作正常.

but when I execute it from terminal, it works fine.

终端命令:sudo Rscript/path/to/script/test.R

如果我在这里遗漏了什么，请告诉我.我试图让它每 5 分钟运行一次.

Please tell me if I am missing something here. I was trying to make it run for every 5 minutes.

推荐答案

Change the permissions 文件/path/to/script/test.R 并确保它有执行权限您尝试提交 cronjob 的用户.

Change the permissions of the file /path/to/script/test.R and make sure, it has execution permissions to the user you are trying to submit the cronjob.

chmod 777/path/to/script/test.R

或者，您也可以尝试下面提到的方法
