shell 脚本和 jQuery

shell scripting and jQuery

提问by user478636

I want to execute a linux command that returns the currently logged on user in linux.

我想执行一个 linux 命令，该命令返回 linux 中当前登录的用户。

Using jQuery and ajax, passing this command to the PHP, which will receive and execute this command using exec()function. The value should be stored and returned.

使用 jQuery 和 ajax，将此命令传递给 PHP，PHP 将使用exec()函数接收并执行此命令。该值应该被存储和返回。

Upon returning, jquery ajax should return it to a contents of a span tag.

返回时，jquery ajax 应将其返回到 span 标记的内容。

How can this be achieved?

如何做到这一点？
