System Administration Guide: Naming and Directory Services (NIS+)

Displaying NIS+ Defaults With `nisdefaults`

The nisdefaults command displays the seven default values currently active in the namespace. These default values are either

Preset values supplied by the NIS+ software
The defaults specified in the NIS_DEFAULTS environment variable (if you have NIS_DEFAULTS values set)

Any object that you create on this machine will automatically acquire these default values unless you override them with the -D option of the command you are using to create the object.

You can use these options to display all default values or any subset of them:

To display all values in verbose format, type the nisdefaults command without arguments.

master% nisdefaults
Principal Name : topadmin.doc.com.
Domain Name : doc.com.
Host Name : rootmaster.doc.com.
Group Name : salesboss
Access Rights : ----rmcdr---r---
Time to live : 12:00:00:00:00
Search Path : doc.com.

To display all values in terse format, add the -a option.
To display a subset of the values, use the appropriate options. The values are displayed in terse mode. For example, to display the rights and search path defaults in terse mode, type the following.
rootmaster% nisdefaults -rs ----rmcdr---r--- doc.com.
To display a subset of the values in verbose mode, add the -v flag.
