Permissions
July 19, 1998
Okay, so in our discussion of the ls -l
option, we promised to explain what we meant by permissions,
owner and group. Well here we go...
Permissions are a basic part of the UNIX
security system. In short, they define who gets to do what with
which files.
Specifically, permissions define who gets to:
- Read a File
- Modify or delete a file
- Execute a file (if it is a program)
Your access privileges are defined in the
password and group files. Before we get into the nitty gritty of
permissions, let's take a look at these files.
