"pwd" --- The password database
*******************************

======================================================================

This module provides access to the Unix user account and password
database.  It is available on all Unix versions.

Availability: Unix, not WASI, not iOS.

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>"):

+---------+-----------------+-------------------------------+
| Index   | Attribut        | Signification                 |
|=========|=================|===============================|
| 0       | "pw_name"       | Nom d’utilisateur             |
+---------+-----------------+-------------------------------+
| 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"        | Répertoire d’accueil de       |
|         |                 | l’utilisateur                 |
+---------+-----------------+-------------------------------+
| 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.

Note:

  In traditional Unix the field "pw_passwd" usually contains a
  password encrypted with a DES derived algorithm.  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.

It defines the following items:

pwd.getpwuid(uid)

   Return the password database entry for the given numeric user ID.

pwd.getpwnam(name)

   Return the password database entry for the given user name.

pwd.getpwall()

   Return a list of all available password database entries, in
   arbitrary order.
