pwd — The password database
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,
||Optional encrypted password|
||Numerical user ID|
||Numerical group ID|
||User name or comment field|
||User home directory|
||User command interpreter|
The uid and gid items are integers, all others are strings.
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
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.
