The ls command is likewise affected. For example, the following command accesses the

group ﬁle to obtain additional information about a group:

ls -lg

If the group is omitted, no group entry will exist and no information will be available.

For this reason, you should use OMIT to omit groups from ﬁle /etc/group only if your

user community is very large and either of the following conditions occur:

• The group ﬁle is taking up too much space.

• Group ID-to-name mapping is too slow (during an ls -lg command, for example).

36.2.3.6 Examples

To override the group ID of group kmem to be 3, use the following entry:

kmem::3:

To override the group password and membership for group system to the single account

root, use the following entry:

system:*::root

36.2.4 Creating Override File Entries

To create override ﬁle entries, edit the passwd_override ﬁle and supply the override

entries. The entry must identify the account (or accounts) to which the override applies

by specifying one of the following keyﬁelds:

principal_name The name of the speciﬁc principal to which to apply the

overrides. The override applies only to the account for the

principal’s primary name. For example, if you specify mahler

as the principal name in an override entry, the overrides apply

only to principal mahler’s account, and not to any accounts for

mahler’s aliases.

principal_uid A UNIX ID that identiﬁes the accounts to which to apply the

override if principal_name is not speciﬁed. The override is

applied to all accounts for the principal that is identiﬁed by

principal_uid, including any accounts for the principal’s aliases.

For example, suppose that principal mahler has a UNIX ID of

2195. If you specify 2195 as the key of the entry, the overrides

apply to all accounts that are associated with that UNIX ID.

Because a principal’s primary name and aliases carry the same

UNIX ID, this means that the overrides apply to accounts for the
