What is the best way to find out the user that a python process is running under?
I could do this:
name = os.popen('whoami').read()
But that has to start a whole new process.
os.environ["USER"]
works sometimes, but sometimes that environment variable isn't set.
回答1:
import getpass
print getpass.getuser()
See the documentation of the getpass module.
getpass.getuser()
Return the “login name” of the user. Availability: Unix, Windows.
This function checks the environment variables LOGNAME, USER, LNAME and USERNAME, in order, and returns the value of the first one which is set to a non-empty string. If none are set, the login name from the password database is returned on systems which support the pwd module, otherwise, an exception is raised.
回答2:
This should work under Unix.
import os
print os.getuid() # numeric uid
import pwd
print pwd.getpwuid(os.getuid()) # full /etc/passwd info
