Cron 在主目录而不是文件目录中运行 [英] Cron is running in home directory instead of file directory

问题描述

我关注了 stackoverflow 中的一些其他帖子，并使用 rvm cron setup 成功地设置了带有 RVM 的 cron，并向 crontab 文件注入了一些 ENV.

I followed some other posts in stackoverflow and successfully setup cron with RVM using rvm cron setup and injected some ENV to the crontab file.

当我对 dotenv gem 不起作用的原因进行故障排除时，我意识到以下几点:

When I was troubleshooting why the dotenv gem is not working, I realised the following:

我将我的 test.rb 放在文件路径 /home/myuser/ruby/test.rb 中，并且我的 crontab 文件如图所示下面:

I placed my test.rb in file path /home/myuser/ruby/test.rb and had my crontab file as shown below:

* * * * * ruby /home/myuser/ruby/test.rb >> /home/myuser/ruby/output.log

当我将 test.rb 的输出与 Dir.pwd 放在一起时.输出表明 rb 在 /home/myuser/ 目录而不是 /home/myuser/ruby 目录中运行.

and when I puts the output of the test.rb with Dir.pwd. The output states that the rb is run in the /home/myuser/ directory instead of /home/myuser/ruby directory.

虽然我通过手动更改路径进行了修补程序.但我想知道为什么会这样.

While I had a hotfix by manually changing the path. But I wonder why it is the case.

推荐答案

默认情况下，用户的 cron 任务是从用户的主目录执行的.为了从正确的目录执行脚本，你必须cd"到它.

By default, cron tasks of a user are executed from the user's home directory. In order to execute the script from proper directory, you have to "cd" to it.

考虑将您的 crontab 更改为:

Consider changing your crontab to:

* * * * * cd /home/myuser/ruby && ruby ./test.rb >> /home/myuser/ruby/output.log
