用tab找到的：查询窗口id的命令。

[eexpress]

$ xwininfo

xwininfo: Please select the window about which you
would like information by clicking the
mouse in that window.

xwininfo: Window id: 0x360001d "exp@exp-laptop: ~"

看来我的截图脚本要修改成这种通用的格式了。md，-all也没有name的信息。xprop又没有id信息。不如fvwnident

$ xprop |grep 'window id # of group'
$ xprop |grep 'WM_CLASS(STRING)'
麻烦
