Mastering SSH Commands for Effective Server Management

Learning SSH commands is crucial for managing Linux servers efficiently. Whether you are a beginner or have some experience, these commands will help you manage your server effortlessly.

Understanding SSH and Its Importance

Secure Shell (SSH) is a protocol that provides a secure channel over an unsecured network. It is widely used for remote server management, allowing users to log into a server, execute commands, and manage files. For beginners, understanding SSH and its basic commands is the first step to mastering server management.

How to Access a Remote Server

Before diving into commands, you need access to a remote server. If you’re using Hostinger, you can find your login details in the Server tab of hPanel for VPS plans or under Hosting -> Advanced -> SSH Access for shared hosting.

SSH connections can be established using an SSH client like PuTTY or through the built-in command prompt on Windows or terminal shell on Linux and macOS. Just enter:

ssh user@serverip

Replace “user” with your username and “serverip” with your server’s IP address. Follow any prompts to complete the connection.

Basic SSH Commands to Know

Here’s a list of essential SSH commands every user should know:

1. ls Command

The ls command lists all files and directories in your current directory. You can use options like -l for detailed information and -a to show hidden files.

11. find Command

Search for files using find [starting directory] [options] [search term]. Use options like -name for specific file names.

12. vi/nano Command

13. history Command

View your command history with history [number] to see the most recent commands you’ve used.

14. clear Command

Clear the terminal screen with the clear command, making your workspace tidy.

15. tar Command

Create or extract archives with tar. Use tar -cvzf [archive.tar.gz] [directory] to create and tar -xvzf [archive.tar.gz] to extract.

16. wget Command

Download files from the web with wget [URL]. Use -i [file] to download multiple files listed in a document.
