python-shutil模块常用方法(42)

>>> import shutil
>>> with open('/etc/passwd','rb') as sfobj:
...     with open('/tmp/mima.txt','wb') as dfobj:
...             shutil.copyfileobj(sfobj,dfobj)    #拷贝文件对象
>>> shutil.copyfile('/etc/passwd','/tmp/mima2.txt')    #拷贝，改名
'/tmp/mima2.txt'
>>> shutil.copy('/etc/passwd','/tmp/') #拷贝到文件夹下，不改名
'/tmp/passwd'
>>> shutil.copy2('/etc/passwd','/tmp/')    #保持属性的拷贝，相当于cp -p
'/tmp/passwd'
>>> shutil.move('/tmp/mima.txt','/var/tmp/')   #移动，相当于mv
'/var/tmp/mima.txt'
>>> shutil.copytree('/etc/security','/tmp/anquan') #拷贝目录，相当于cp -r
'/tmp/anquan'
>>> shutil.rmtree('/tmp/anquan')   #删除目录，相当于rm -rf
>>> shutil.copymode('/etc/shadow','/tmp/mima2.txt')    #保持权限不变的拷贝
>>> shutil.copystat('/etc/shadow','/tmp/mima2.txt')    #元数据要使用stat查看
>>> shutil.chown('/tmp/mima2.txt',user='zhangsan',group='zhangsan')    #设置所属者，所属组
