linux - 如何使用 xdg-open 将应用程序置于最前面

Question

在 Linux 上，xdg-open 可以启动一个应用程序，但在大多数情况下，所需的行为是仅在应用程序尚未运行时启动它，如果它已经在运行则将其置于最前面。

xdg-open 可以做到这一点吗？是否有其他一些标准方法来提供此功能？

Answer 1

如您所见，xdg-open 只不过是处理文件类型并在首选应用程序中打开它的包装器。是否支持"bring to front" 选项取决于应用程序。

$ file /usr/bin/xdg-open
/usr/bin/xdg-open: POSIX shell script, ASCII text executable

为了将应用程序窗口置于最前面，您可以使用其他工具，如 wmctrl、xdotool 或 qdbus。

       ager that is compatible with the EWMH/NetWM specification.  wmctrl  can

NAME
       xdotool - command-line X11 automation tool

SYNOPSIS
       xdotool cmd args...

       Notation: Some documentation uses [window] to denote an optional window
       argument. This case means that the argument, if not present, will
       default to "%1". See "WINDOW STACK" for what "%1" means.

DESCRIPTION
       xdotool lets you programatically (or manually) simulate keyboard input
       and mouse activity, move and resize windows, etc. It does this using
       X11's XTEST extension and other Xlib functions.

       There is some support for Extended Window Manager Hints (aka EWMH or
       NetWM).  See the "EXTENDED WINDOW MANAGER HINTS" section for more
       information.
