Free System Administration Training

I recently attended some free online training from Oracle. Oracle called the training event Virtual SysAdmin Day.  I thought the training was really good. So I'm posting links to the training so maybe you can also benefit from the training as well.

Adding, Deleting or Changing a Group in UNIX

This is a little how to on creating, deleting or modifying a group on a UNIX based computer.

root@earth> /usr/sbin/groupadd -g # groupname
If you us -g the option, you will be able to set the GID for the group. If the GID is not set then the OS will choose one.

To delete a group.
root@earth> /usr/sbin/groupdel groupname

To change a group
root@earth> /usr/sbin/groupdel -g # -n newgroupname groupname
Use the -g option to change the group gid and use -n to change the name of the group.

Use these commands only for local accounts. If a network nameservice or directory server is running then use that service instead.
