Snowleopard 截屏

忽然发现截屏不好使了！！ ctrl-shift-cmd-3/4，都没效果！ 尝试了改defaults read com.apple.screencapture 居然什么都没有- -！ 问题还没解决，先记下！ 

不过塞翁失马焉知非福阿，HOHO，发现了个更方便的小东西！ 

其实截屏是有cli的，/usr/sbin/screencapture，可以man screencapture 看具体参数，截屏最常用的其实就是：       

• screencapture /my/path 截全屏，另存为文件/my/path！ 
• screencapture -i /my/path 自定义选取
• screencapture -w /my/path 窗口选择模式

若想存入剪切板而不是文件，搭配参数c即可，如

• screencapture -c
• screencapture -ci
• screencapture -cw
