我不是开发人员，也不是与IT密切相关的人，我是医学生，我只是想使用sed shell命令使用Tasker编辑xml文件（电报通知共享首选项）。 这是xml文件：

所以我正在测试txt文件，命令如下：
sed -i 's+"EnablePreviewAll" value="false"/>+"EnablePreviewAll" value="true"/>+' /storage/emulated/0/basel.txt
它没有给我一个错误，但是值完全没有变化。 （我使用具有根访问权限的Termux） （我复制了文本并将其命名为basel.txt进行测试）
答案 0 :(得分：0)
这可能对您有用（GNU sed）：
sed -i '/EnablePreviewAll/s/false/true/' file
如果一行包含EnablePreviewAll，则将false替换为true。
