passwd(5) |
 |
passwd − password file
Passwd contains for each user the following information:
|
name (login name, contains no upper case) |
||
|
encrypted password |
||
|
numerical user ID |
||
|
numerical group ID |
||
|
GCOS job number, box number, optional GCOS user-id |
||
|
initial working directory |
||
|
program to use as Shell |
This is an ASCII file. Each field within each user’s entry is separated from the next by a colon. The GCOS field is used only when communicating with that system, and in other installations can contain any desired information. Each user is separated from the next by a new-line. If the password field is null, no password is demanded; if the Shell field is null, the Shell itself is used.
This file resides in directory /etc. Because of the encrypted passwords, it can and does have general read permission and can be used, for example, to map numerical user ID’s to names.
