passwd(5) |
 |
passwd password file contains for each user the
following information: name (login name, contains no upper
case) encrypted password numerical user ID numerical group
ID (for now, always 1) 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. /etc/passwd login (I), crypt
(III), passwd (I), group (V)
