Introduction

Managing files on a server often requires editing configuration or text files through the command line. When accessing your server via SSH, text editors like Nano, Vim, and Emacs allow you to view and modify these files directly in the terminal. This guide will introduce you to basic commands and usage of these text editors, specifically focusing on Nano and Vim, which are commonly pre-installed on most Linux servers. This guide is for users who need to manage server files or configurations but are unfamiliar with terminal-based text editing.

Prerequisites

• Access to a Linux-based server via SSH.
• Basic familiarity with using the terminal.
• User privileges to modify system or configuration files on the server.

Step-by-step guide

Step 1: Connect to your server via SSH

• Open your terminal.
• Run the following command, replacing your_server_ip with your server’s IP address:

ssh username@your_server_ip

• After entering your password, you will be logged into your server.

Using Nano Text Editor

Nano is a beginner-friendly text editor that is simple to use with a few basic commands. It’s usually installed by default on most Linux distributions.

Step 2: Open a file with Nano

• To open a file in Nano, run the following command:

sudo nano /path/to/your/file

Step 3: Edit the file

• To insert text, simply type where your cursor is placed.
• To delete text, position the cursor on the text and use the Backspace or Delete key.

Step 4: Save and exit Nano

• When you’re done editing, press Ctrl + X to exit.
• You will be asked if you want to save the changes. Press Y for yes or N for no.
• If you choose to save, press Enter to confirm the file name and exit.

Using Vim Text Editor

Vim is a more advanced text editor, often used by power users for its extensive features. It may take more time to learn, but it is very powerful for managing files.
