Commands Reference, Volume 3

lsgroup Command


Displays group attributes.


lsgroup [ -R load_module ] [ -c | -f ] [ -a List ] {ALL | Group [ ,Group ] ...}


The lsgroup command displays group attributes. You can use this command to list all the system groups and their attributes or you can list all the attributes of individual groups. Since there is no default parameter, you must enter the ALL keyword to list all the system groups and their attributes. All the attributes described in the chgroup command appear. If the lsgroup command cannot read one or more attributes, it lists as much information as possible. To view a selected attribute, use the -a List flag.

Note: If you have a Network Information Service (NIS) database installed on your system, some user information may not appear when you use the lsgroup command.

By default, the lsgroup command lists each group on one line. It displays attribute information as Attribute=Value definitions, each separated by a blank space. To list the group attributes in stanza format, use the -f flag. To list the information in colon-separated records, use the -c flag.

You can use a Web-based System Manager Users application (wsm users fast path) to run this command. You could also use the System Management Interface Tool (SMIT) smit lsgroup fast path to run this command.


-a List Specifies the attributes to display. The List parameter can include any attribute defined in the chgroup command, and requires a blank space between attributes. If you specify an empty list, only the group names are listed.
-c Displays the attributes for each group in colon-separated records, as follows:

#name:  attribute1:  attribute2:  ...
Group:  value1:      value2:      ...
-f Displays the group attributes in stanzas. Each stanza is identified by a group name. Each Attribute=Value pair is listed on a separate line:

-R load_module Specifies the loadable I&A module used to get the group attribute list.


Access Control: This command should be a general user program with execute (x) access for all users. Attributes are read with the access rights of the invoker, so all users may not be able to access all the information. This depends on the access policy of your system. This command should have the trusted computing base attribute.

Listing a group may not be supported by all loadable I&A modules. If the loadable I&A module does not support listing a group, then an error is returned.
