Learning how to edit text files in the console and from the Raspbian GUI is a rite of passage for new Raspberry Pi owners.

It's all part of learning how computers really work. A secret that most computer makers don't tell you is that underneath all the gloss and shine of modern operating systems, it's all text. Every menu, every button, and every setting of every program started as a text document somewhere.

In Raspbian, which is based on Debian Linux, you are far more likely to need to edit text files than on computers running MacOS or Windows. This is a great thing. It lets you get under the hood and really see what's going on.

How to edit text files on a Raspberry Pi

You may remember the days when computers had text-based interfaces, or you may have only pushed buttons and tapped icons until now. No matter – you will now need to edit text.

There are a lot of different ways to edit text, and everybody has their own favourites. Here were going to look at the two main options: Text Editor (also called Leafpad) and Nano.

STEP-01: Viewing text

We've downloaded the release notes for the latest version of Raspbian to view and edit. You can get them from magpi.cc/2ejN6sk. Right-click and save the file to your Pi folder. Open a Terminal window. Open the File Manager and double-click the release_notes.txt file to view it in Text Editor.

STEP-02: Using cat

Often you'll be working with text files from the command line. The way to do this is using cat (short for ‘concatenate'). Open the Terminal and enter cat release_notes.txt. The text will fly up off the top of the screen. To view the text one page at a time, pipe it through more and press SPACE to move one page at a time.

cat release_notes.txt | more

STEP-03: Open text

You can open a text file in Text Editor from the command line using xdg-open (this will open a file in its default associated app).

xdg-open release_notes.txt Switch genesis emulator.

This is a handy compromise between working on the command line and text editing in a friendly graphical environment. It's the best way to edit text files when you first start.

STEP-04: Nano

You won't always have access to the GUI when working in the command line, and you should quickly learn to edit text files without heading to the GUI. The way to do this is using a text editing app called Nano.

nano release_notes.txt

STEP-05: Cut and paste

Nano works just like a word processor – although, without a cursor and interface, you may find it quirky. Move around with the arrows and enter and delete text. You can cut lines of text using CTRL+K and paste with CTRL+U.

STEP-06: Save and close

When you've finished editing a text file, you save it using the Writeout function. Press CTRL+O and enter Y to save the file. Use CTRL+X to exit and close Nano and return to the command line.

The 64-bit versions of Windows do not support the edit command in the Windows command line. If you need to edit files from the command line, we suggest using the notepad command from the command line as shown in the example below.

Running the above command would edit the hope.txt file if it exists or create a new file called hope.txt in notepad. Once the file is saved, that file will be created in your current directory.

Tip

Using the start command, you can also start another text editor with any file. For example, start hope.txt would open hope.txt in the default text editor.

Additional information

• See the edit command page for additional information about this command and its syntax.

The MS-DOS text editor, edit, allows you to view, create, or modify any text file on your computer. While running edit, a screen similar to the picture below is shown.

Availability

Edit is an external command available for the following Microsoft operating systems.

Note

The edit command is a legacy 16-bit program, which is incompatible with 64-bit operating systems. Therefore, 64-bit versions of Windows do not come installed with, and cannot run, the edit command. On 64-bit Windows systems, use Notepad to edit files instead. See: Why is the edit command missing in Windows?

Edit syntax

/B	Forces monochrome mode.
/H	Displays the maximum number of lines possible for your hardware.
/R	Load file(s) in read-only mode.
/S	Forces the use of short file names.
/	Load binary file(s), wrapping lines to characters wide.
/?	Display a summary of command line options.
[FileName..]	Specifies initial files(s) to load. Wildcards and multiple file specs can be given.

Edit examples

Open the file c:autoexec.bat to be edited, if it exists. If the file does not exist, a blank blue screen is shown.

Note

If you are using new versions of Windows running under a 64-bit processor, the edit command no longer works. See: How to open, view, and edit the contents of a file on a computer.

Using 'copy con'

If you are running an MS-DOS version 4.x or lower or you cannot find edit.com on your hard drive, you can also use the following command to create a file.

Once you have entered the command above, a file with the name specified is created.

Once you have typed all the lines you want to be in the file, press and hold Ctrl+Z. Once you see '^Z' on the screen, press Enter and one file should be copied.

Using edit to create a new file

Using edit, you can also create a new file. For example, if you wanted to create a file called myfile.txt, you would type the command below.

This command would bring up a blank edit screen. Type your text and save the file, and myfile.txt will be created with the text you entered.

Additional information

• Edit is only able to open a file with a maximum of 65,280 lines.
• If your mouse drivers are not loaded while in MS-DOS or the Windows command line, you may have no mouse support. It is still possible to navigate the Editor using shortcut keys as seen in the below list.
• Pressing Alt allows you to quickly navigate through edit without having to memorize all the commands listed below.
