Editing text files from the command line

Editing Text Files from the Command Line

You can edit text files in your Ruachost.com control panel, but it’s often faster and more efficient to do it directly from the command line. This guide shows how to use the Nano and Vim editors to modify text files quickly.

Choosing an Editor

Nano is simpler and ideal for beginners, while Vim offers more advanced features and flexibility once you get comfortable. You can try both and use whichever suits your workflow best.

Note:
If this is your first time using the command line, it’s a good idea to review some basic Linux commands before continuing.

Using the Nano Editor

Editing files with Nano is straightforward. To open a file, use this command:

bash

nano filename

Replace filename with the name of the file you want to edit.

Note:
If the specified file doesn’t exist, Nano automatically creates it.

Once the file opens, you can start typing immediately to make changes.

• Use the arrow keys to move around.

• Press Ctrl + V to scroll forward and Ctrl + Y to scroll backward.

When you’re done editing:

• Press Ctrl + O to save changes.

• Press ENTER to confirm the filename.

• Press Ctrl + X to exit.

For help inside Nano, press Ctrl + G.

Using the Vim Editor

To open a file in Vim, type:

bash

vi filename

Note:
The command vi is linked to Vim. “Vi” is one of the earliest Unix text editors, and “Vim” stands for Vi Improved. You can type either vi or vim — both work the same way.

When Vim opens, it starts in normal mode, meaning it interprets keystrokes as commands rather than text input.

To start typing:

1. Press i to enter insert mode.

2. You’ll see --INSERT-- at the bottom of the screen.

3. Make your edits. Use the arrow keys or Page Up/Page Down to move around.

To stop editing and return to normal mode, press ESC. The --INSERT-- indicator disappears.

To save or exit:

• :w → Save changes without exiting.

• :q → Quit without saving.

• :wq → Save and quit at the same time.

Tip:
To access a built-in Vim tutorial, type vimtutor at the command line.
