New page

UNIX groups are useful for sharing file and directory permissions with other users in the UMIACS system. Each UMIACS account is by default a member of its own group, defined by that username. An account can be made member to any number of additional groups.

===Creating Groups & Adding Users===
A user may create up to 5 UNIX groups via the [https://intranet.umiacs.umd.edu/directory/groups/ Directory tool].
#Click ''Create UNIX Group'' on the Groups [https://intranet.umiacs.umd.edu/directory/groups/ page]
#Enter in the group name and a brief description of what the organization of users in the group is for, then click create group.
#Click on the link of the newly created group, add a valid UMIACS user into the available text box, click add user. '''NOTE: '''The user creating the group is not added to that group by default, and must be explicitly added after creation.

===Applying the Group===
*In order to apply the group to a file or directory to which you want to grant all members some set of permissions use the command
:<code>chgrp ''group-name'' ''file-name''</code>
This will grant the specified group group-ownership of the file, at the level of access that the previous group possessed.

===Verifying and Changing Group Permissions===
*To see the permissions that the group has for a specific file/directory use <code> ls -l </code> and the group permissions will be the 5,6,7th characters.
*To change the permissions of the group on that file/directory, if you own the group, use
:<code>chmod g+''r/w/x'' ''file-name'' </code>

===Deleting Groups===
Deleting groups will be managed by UMIACS staff. If you would like to delete a group, please submit a ticket through [[Jira|JIRA]].
