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 |
Attribute |
Znaczenie |
---|---|---|
0 |
|
Login name |
1 |

Optional encrypted password |
2 |

Numerical user ID |
3 |
|
Numerical group ID |
4 |
|
User name or comment field |
5 |

User home directory |
6 |

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.
Informacja
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.
