获取在Linux中打开的应用程序窗口的数量

我想要检测由窗口pipe理器pipe理的特定应用程序有多less个实例被打开。 目前，我有这个：

#!/bin/bash # wmctrl required pids=$(pidof $1) IFS=' ' read -a pid_arr <<< "$pids" matches=0 for pid in "${pid_arr[@]}" do matching_lines=$(wmctrl -l -p | egrep -c "^.+\b.+\b$pid\b") matches=$((matches + $matching_lines)) done echo $matches 

说我有firefox打开三次，我传递firefox作为参数，function将只返回正确的数字，如果没有“子窗口”（如偏好窗口）打开。 否则，函数也会计算这些窗口。

我想获得没有“子窗口”的窗口数量。

PS：做了一些改变。 要计算没有对话窗口的窗口数量，这是我目前的解决scheme：

• C / Linux – 服务器< – >与命名pipe道的terminal通信
• “权限被拒绝”在启动时运行命令
• bash脚本：如何find“symlink / ..”的绝对path？
• 不能得到任何答复dbus发送
• 等到服务以bash脚本开始

 #!/bin/bash pids=$(pidof $1) IFS=' ' read -r -a pid_arr <<< "$pids" matches=0 for pid in "${pid_arr[@]}" do ids=$(wmctrl -l -p | awk '$3=='$pid'{printf $1" "}') IFS=' ' read -r -a id_arr <<< "$ids" for id in "${id_arr[@]}" do if ! xprop -id "$id" | egrep -q '(WM_TRANSIENT_FOR|_NET_WM_WINDOW_TYPE_DIALOG)' then ((matches++)) fi done done echo $matches 

但在Firefox的情况下，脚本无法区分浏览器窗口和其偏好窗口，因为它们都不是一个对话窗口。

上面的脚本对我来说已经足够了，因为我用它来确定xfce4-appfinder有多less个窗口（没有对话窗口）。 对于xfce4-appfinder，脚本可以工作，因为它的首选项窗口很容易被识别为对话窗口。 在Firefox中，首选项窗口甚至可以通过调用firefox -preferences来单独打开。 把窗户这样的窗口识别为某种“子窗口”也许是不可能的。

这里是我的浏览器和Firefox的首选项窗口xprop和xwininfo结果：
