Groups allow sets of users to share files. The group permissions on a file or directory determine whether members of a group can access them.
You can set the group of a file or directory by changing its
properties from the desktop
or by using the
chgrp(1)
command.
For more information on the desktop, see
``Using the CDE desktop''.
A user can be a member of several groups at once, and can access any file or directory that is within their group set (if group permissions allow). This membership set is known as the ``supplemental group list''. By default, files created by a user have the group ID of their login group. Users can change their current working group (also known as effective group ID) with the newgrp(1M) command.
