如何测试cron作业？ [英] How to test a cron job?

问题描述

我使用的是Ubuntu Linux 10.0.4。我想每6小时，每天运行一个脚本。当我发出 sudo crontab -e 时，我看到：

I'm using Ubuntu Linux 10.0.4. I want to run a script every 6 hours, every day. When I issue sudo crontab -e, I see:

# m h  dom mon dow   command
* 00,06,12,18 * * * /opt/scripts/selenium/run_nis_inf_tests.sh

但是，我没有看到我的脚本的预期结果，我甚至不确定如果它的运行。有没有办法测试，短缺等待指定的时间，脚本正常运行。或者，我如何查看脚本生成的错误？ - Dave

However, I'm not seeing the expected outcome from my script, and I'm not even sure if its running. Is there a way to test, short of waiting until the specified time, that the script is running properly. Or, how can I view the errors the script is generating? - Dave

推荐答案

您可以将MAILTO变量更新为您的电子邮件地址，cron应通过电子邮件向您发送任何STDOUT和STDERR输出。还要检查您的syslog文件/ var / log / messages以查看脚本是否由cron执行。

You can update the MAILTO variable to your email address, and cron should email you any STDOUT and STDERR output. Also check your syslog file /var/log/messages to see if the script is being executed by cron.
