/etc/fstab 1 /etc/grub.conf

From the man page: /etc/group is an ASCII file which defines the groups to which users belong. There is one entry per line, and each line has the format:

group_name:passwd:GID:user_list

The field descriptions are:

• group_name: The name of the group.
  
  
• password: The (encrypted) group password. If this field is empty, no password is needed.
  
  
• GID: The numerical group ID.
  
  
• user_list: All the group member’s user names, separated by commas.

An example of the group file:

root:x:0:root

bin:x:1:root,bin,daemon

apache:x:48:aflores,asolombr,cmilford,lsuarez,rmorales,tbowe

tbowe:x:502:

mdavis:x:503:

aflores:x:504:

slucio:x:505:

Notice that the group apache has several users added. All of these users would be able to access files and directories that have the group apache according to the group access privileges that will be discussed in the next section.
