Python OS模块错误

Question

在Python2.7中，以下代码不起作用：

import os

def dockSuck():
    os.system("echo Switching to suck effect.")
    os.system("defaults write com.apple.dock mineffect suck")
    os.system("killall dock")

dockSuck()

它打印出Switching to suck effect.和No matching processes belonging to you were found。它应该将最小化效果(在Mac上)切换到隐藏的吸取效果(然后通过killall对其重新设置码头)，但是它会返回一个错误。

Answer 1

osx上的dock进程名为Dock -注意大写。

$ ps -ef |grep dock -i
  501   359     1   0 17Oct14 ??         0:57.16 /System/Library/CoreServices/Dock.app/Contents/MacOS/Dock
  501   423     1   0 17Oct14 ??         0:03.09 /System/Library/CoreServices/Dock.app/Contents/XPCServices/com.apple.dock.extra.xpc/Contents/MacOS/com.apple.dock.extra
  501  2259   359   0 17Oct14 ??         0:37.98 /System/Library/CoreServices/Dock.app/Contents/Resources/DashboardClient.app/Contents/MacOS/DashboardClient

将killall语句修改为os.system("killall Dock")
