python 取得当前用户的主目录(sudo)

'sudo' changes enviroment variables ,such as : os.environ['HOME'], etc

我的电脑Home目录为 /home/wsh

 加入脚本为evir.py

import osif __name__ == "__main__":     print 'wsh'+os.environ['HOME']    print 'wsh'+ os.path.expandvars('$HOME')    print 'wsh'+ os.path.expanduser('~')

执行此脚本。有两种结果


执行此脚本。有两种结果

1 。 直接执行 treminal 输入：

python envir.py

结果：

wsh /home/wshwsh /home/wshwsh /home/wsh

2。 加上sudo指令

sudo  python envir.py

结果：
 

wsh /rootwsh /rootwsh /root

so just use:

os.getlogin()

in conclusion:

  if you want to get current user home  in linux , while you have to get 'sudo' permission. that is to say . you need sudo to start up your python script.

just use "os.getlogin()", since other commands are changed because of sudo. then use can just to get current home directory use:

'/home/'+os.getlogin()
