[英]How can I determine if my KDE Desktop is in lock screen state from command line?
I have a program run on the background that simply take a screenshot every N seconds.我有一个在后台运行的程序,它每 N 秒简单地截取一次屏幕截图。
eg:例如:
#!/bin/sh
while true; do
take-screenshot
sleep 10
done
What I want to achieve is only take screenshot if screen is not locking.我想要实现的只是在屏幕未锁定时截取屏幕截图。 eg:
例如:
#!/bin/sh
while true; do
if ! screen-is-locking; then
take-screenshot
sleep 10
fi
done
How can I determine if my desktop is locking in command line?如何确定我的桌面是否在命令行中锁定?
According to this link provided by fellow comments under this question, I got a solution or workaround for my question, it works well under 5.4.58-1-MANJARO KDE Plasma (other DE might have different ways according to that answer's statement).根据此问题下的其他评论提供的链接,我为我的问题找到了解决方案或解决方法,它在 5.4.58-1-MANJARO KDE Plasma 下运行良好(根据该答案的声明,其他 DE 可能有不同的方法)。
There's a method in dbus service which well fit my need: dbus 服务中有一种方法非常适合我的需要:
#/bin/sh
is_screen_locking()
{
if dbus-send --session --dest=org.freedesktop.ScreenSaver --type=method_call --print-reply /org/freedesktop/ScreenSaver org.freedesktop.ScreenSaver.GetActive | grep 'boolean true' > /dev/null; then
return 0
else
return 1
fi
}
if is_screen_locking; then
echo 'screen is locking'
else
echo 'screen is not locking'
fi
