Bash Shell脚本文本重定向权限

bash shell ubuntu

Bash Shell脚本文本重定向权限,bash,shell,ubuntu,sh,ubuntu-18.04,Bash,Shell,Ubuntu,Sh,Ubuntu 18.04,我正在尝试安装新的cyberpower UPS，我正在编写一些shell脚本来处理通知和关机。我想让脚本写入日志文件，以跟踪所有电源事件。出于某种原因，如果我直接调用该脚本，它将正确地记录到文本文件中，但是，当我的UPS调用该脚本时，它不会写入日志文件，因此我猜可能存在权限问题。这些都是在Ubuntu 18.04上运行的。另外，shutdown.sh脚本永远不会运行，无论主脚本如何调用。但是每次都会正确调用pwrstatd email.sh。任何帮助都将不胜感激 #!/bin/bash . /e

似乎成功了

几个问题：UPS如何“调用”这个脚本？您的用户id与UPS用户id是什么？你的工作目录是什么？pwrstatd email.sh的内容是什么？我添加了一些编辑。脚本位于
/usr/local/bin/
我不确定UPS调用脚本时使用了什么，文档不是非常清晰，细节非常重要。你安装了一个软件包，还是使用了Ubuntu的内置功能？我从这个问题下载的软件包可能更适合。谢谢，这有点帮助，但我能告诉你它是以
root
身份运行的，所以不知道为什么它不能写入该文件谢谢，我确实得出了关于退出0的结论，我从
pwrstatd email.sh
文件中删除了它，并且能够运行
shutdown.sh
脚本。但是，我对
.txt
文件的权限仍然存在问题。如果您运行
id>/tmp/ups.txt
code，
id
将告诉您脚本以什么用户身份运行。它可能不是以
root
的身份运行的，但我将结束这个问题。我同意rtx13，这可能更适合超级用户。有几个建议。1.不要将日志文件放入
/usr/local/bin
，因为该目录是为程序保留的。日志可能会进入
/var/log/ups
或类似目录。2.如果将
/var/log/ups
创建为root用户，然后将该目录的所有者更改为与运行脚本的用户相同的用户，则您将没有写入文件的权限，也不必使用
sudo dd
。
