This module provides access to the Unix user account and password database. It is available on all Unix versions.
Password database entries are reported as a tuple-like object, whose attributes correspond to the members of the passwd structure (Attribute field below, see <pwd.h>):
|1||pw_passwd||Optional encrypted password|
|2||pw_uid||Numerical user ID|
|3||pw_gid||Numerical group ID|
|4||pw_gecos||User name or comment field|
|5||pw_dir||User home directory|
|6||pw_shell||User command interpreter|
The uid and gid items are integers, all others are strings. KeyError is raised if the entry asked for cannot be found.
In traditional Unix the field pw_passwd usually contains a password encrypted with a DES derived algorithm (see module crypt). However most modern unices use a so-called shadow password system. On those unices the pw_passwd field only contains an asterisk ('*') or the letter 'x' where the encrypted password is stored in a file /etc/shadow which is not world readable. Whether the pw_passwd field contains anything useful is system-dependent. If available, the spwd module should be used where access to the encrypted password is required.
It defines the following items:
Return the password database entry for the given numeric user ID.
Return the password database entry for the given user name.
Return a list of all available password database entries, in arbitrary order.
