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中的其他文章，并使用 rvm cron setup 使用RVM成功设置了cron，并将一些ENV注入到crontab文件中.

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.

当我对为什么 dotenv gem不能正常工作进行故障排除时，我意识到了以下几点:

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

我将 test.rb 放置在文件路径/home/myuser/ruby/test.rb 中，并显示了我的 crontab 文件，如下所示下方:

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 一起放置时.输出表明rb在/home/myuser/目录中运行，而不是在/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获得了修补程序.但是我不知道为什么会这样.

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，您必须"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
