The following fields have size limitations as noted:
• Login name field can be no longer than 8 characters;
• Initial working directory field can be no longer than 63 characters;
• Program field can be no longer than 44 characters.
• Results are unpredictable if these fields are longer than the limits specified above.
The following fields have numerical limitationsas noted:
• The user ID is an integer value between 0 and UID_MAX-1 inclusive. As a special case -2 maybe
present.
• The group ID is an integer value between 0 and UID_MAX-1 inclusive. As a special case -2 maybe
present.
• If either of these values are out of range, the getpwent(3C) functions reset the ID value to
(UID_MAX).
EXAMPLES
NIS Example
Here is a sample /etc/passwd file:
root:3Km/o4Cyq84Xc:0:10:System Administrator:/:/sbin/sh
joe:r4hRJr4GJ4CqE:100:50:Joe User,Post 4A,12345:/home/joe:/usr/bin/ksh
+john:
-bob:
+@documentation:no-login:
-@marketing:
+:::Guest
In this example, there are specific entries for users root and joe, in case the Network Information Sys-
tem are out of order.
• User
john’s password entry in the Network Information System is incorporated without
change.
• Any subsequent entries for user bob are ignored.
• The password field for anyone in the netgroup documentation
is disabled.
• Users in netgroup
marketing are not returned by getpwent(3C) and thus are not allowed to
log in.
• Anyone else can log in with their usual password, shell, and home directory, but with a gecos
field of Guest.
