【问题描述】:
我想通过 Applescript 捕捉我的第二台外接显示器的整个屏幕。当我按下 CMD + SHIFT + 3 时,我会从每台显示器获得两张图像。
有什么建议吗?
谢谢 克里斯

尝试只删除第一个监视器的文件:
screencapture monitor1.png monitor2.png;rm monitor1.png
-m 只捕获主监视器,但没有指定另一个监视器的选项:
$ screencapture -h
screencapture: illegal option -- h
usage: screencapture [-icMPmwsWxSCUtoa] [files]
-c force screen capture to go to the clipboard
-C capture the cursor as well as the screen. only in non-interactive m
odes
-d display errors to the user graphically
-i capture screen interactively, by selection or window
control key - causes screen shot to go to clipboard
space key - toggle between mouse selection and
window selection modes
escape key - cancels interactive screen shot
-m only capture the main monitor, undefined if -i is set
-M screen capture output will go to a new Mail message
-o in window capture mode, do not capture the shadow of the window
-P screen capture output will open in Preview
-s only allow mouse selection mode
-S in window capture mode, capture the screen not the window
-t<format> image format to create, default is png (other options include pdf,
jpg, tiff and other formats)

【讨论】:
man 页面找出如何定位 other 监视器:使用附加的位置文件名参数。虽然没有直接支持的跳过监视器的方法,但有两个技巧:(a) 使用相同的文件名两次,依赖于文件的写入顺序,这样最后一个监视器以“获胜”为目标(尽管这是一个可能不想依赖的实现细节),(b)指定/dev/null作为第一个文件名;虽然这可行,但需要注意的是会报告错误消息并且退出代码为 1,因此很难检测到实际故障。
