Unix

family of operating systems

A family of operating systems from which Linux and macOS are derived. Common features: everything is a file, owner/group/other permissions, small tools combined via pipelines.

Why it matters

Our entire server runs on Linux. Permissions, file ownership, and processes are everyday concerns during any outage.

What's missing without it

Without understanding permissions, you can either break a working service or leave a directory open for write access to everyone.

When it is used

Whenever working on a server, diagnosing failures, or deploying applications.

How we use it

Permissions `755` on directories and `644` on files are standard for websites; `777` means anyone can write — and that's an invitation to trouble.
