Emacs for beginners
Now that we have installed Emacs on the Linux system, let’s get familiar with the basics of using this powerful text editor.
To launch Emacs, open your terminal and simply type emacs. This command opens Emacs with its graphical interface. If you prefer to use Emacs within the terminal, you can launch it in terminal mode by using the command:

- CTRL + b : Move backward one character (similar to pressing the left arrow).
1: Opening and Closing Files
To open a file in Emacs, use the CTRL + x followed by CTRL + f command, then type the file name and press Enter. In case the file doesn’t exist, Emacs will create a new file using the given name.
To close a file, use the CTRL + x followed by CTRL + k command.
2: Editing Text
Editing text in Emacs is similar to other text editors but with different shortcuts:
- CTRL + d : Erase the character found under the cursor.
- CTRL + k : Erase from the current cursor position to the end of the line.
- CTRL + w : Cut the selected text.
- ALT + w : Copy the selected text.
- CTRL + y : Paste the copied or cut text.
3: Saving Files
To save the file you are working on, use the CTRL + x followed by CTRL + s command.
4: Exiting Emacs
To exit Emacs, use the CTRL + x followed by CTRL + c command. When there are any unsaved changes, Emacs will ask you to save them before you exit.
5: Getting Help
Emacs has an extensive built-in help system. Press CTRL + h followed by t to open a tutorial. For a list of commands, press CTRL + h followed by b.
Emacs is a long-standing text editor that offers great flexibility, allowing you to customize it according to your preferences and needs. It can be tricky to learn because there are so many shortcuts and features, but once you get familiar with emacs commands on Linux for beginners, it’s a super powerful tool that can make your work easier, no matter if you are coding, writing, or managing files.
