Linux File Permissions

[ Thanks to Ian MacGregor for this link. ]

"If you are the only user on your Linux box, you may be wondering what's the point of having all these permissions (or lack thereof) that restrict your access to your very own penguin OS. However, before pulling your hair off, you must keep in mind Linux is designed to be a multi-user environment. In an environment with more than one user, it is crucial to have a secure system for deciding which files are yours and who can fiddle with them.

"Even if you're the only user on an ordinary desktop system, file permissions help keep your important files safe, both from outsiders and your own mistakes.

"Understanding file ownership
Every file on your Linux system, including directories, is owned by a specific user and group. Therefore, file permissions are defined separately for users, groups, and others."
