The Group File
July 19, 1998
The group file contains information about
UNIX groups. UNIX groups allow multiple users to be
related for security purposes. This is best seen by example.
Imagine a situation in which
all engineers can modify technical notes, but marketing employees
can only read them. They cannot modify them. Thus, there are
two groups: marketers and engineers, each with different rights
in the system.
The group file is also a colon delimited file of
multiple lines which looks something like this:
engineers:*:101:selena gunther eric
The fields are:
group name:password:group id:users
So how do you know who you are?
