Linux Server Basics

A VPS is usually a Linux machine you control remotely. Basic server work means understanding files, processes, users, packages, and logs.

Common commands:

pwd
ls -la
df -h
free -m
top
sudo apt update

Important directories:

/etc — system and service configuration
/var/log — logs
/var/www — common web root location
/home — user directories

TIP

Before changing config, copy the original file or use version-controlled deployment files.

Linux Server Basics

A VPS (Virtual Private Server) is basically a Linux computer you access remotely instead of sitting in front of. Learning a handful of basic commands lets you look around, check on its health, and install things.

The must-know commands

pwd          # where am I right now?
ls -la       # what's in this folder?
df -h        # how much disk space is left?
free -m      # how much memory is used?
top          # what's running, and how busy is the CPU?
sudo apt update && sudo apt upgrade   # get the latest software updates

top in particular is your go-to when something feels slow — it shows exactly what’s eating CPU or memory right now.

Places worth knowing

/etc — configuration files for the system and installed services.
/var/log — log files (your first stop when debugging).
/home — each user’s personal folder.

Before you edit a config file

TIP

Before changing a system configuration file, make a backup copy first (cp file file.bak). If your change breaks something, you can instantly put the original back.

In one sentence

A VPS is a remote Linux machine — a handful of commands (ls, df, top, apt update) let you explore it, check its health, and keep it updated, and it’s always worth backing up a config file before you edit it.
