Passwd (database)

Passwd (database)

passwd is a name service database used to store user account information on Unix-like operating systems.

The sources for the passwd database (and hence the sources of user accounts on a system) are configured, like other name service databases, in nsswitch.conf.

Command line

The getent command can be used to fetch passwd information.

Fetching a list of all available users

getent passwd

Fetching a specific user entry

For a specific user called 'joe':

getent passwd joe

Python

The 'pwd' module can be used. [http://docs.python.org/lib/module-pwd.html]
