What is a Text Editor in Linux?

A text editor also referred to as a code editor, is an application designed for coding and editing in HTML, CSS, JavaScript, PHP, and many other programming languages. Most editors accompany features like Syntax highlighting, easy navigation, customizable interfaces, search and replace options, and so on.

In Linux, there are two sorts of text editors:

  • Command-line text editors. A simple example is Vim, which allows you to jump into the editor from the instruction. System admins will find this very useful when editing configuration files.
  • Graphical interface (GUI) text editors. This sort of text editor features a GUI but can’t be used from the instruction.

There are two command-line text editors in Linux®: Vim and nano.

You can use one of these two available options. Do you ever have to write a script, edit a configuration file, create a virtual host, or jot a quick note for yourself? These are but a couple of samples of what you’ll do with these tools.

While these tools might sound daunting initially, any Linux user should become familiar with using a minimum of one. Ask any Linux Administrator or regular user, and you soon find that everybody has their favourite.

This article covers the fundamentals of every editing tool and the way they differ.

Vim

Vim comes from Vi Improved because it’s the successor of an older editor called vi. Because this editor (through its predecessor) has been around an extended time, Linux Administrators or coders usually favour it. Vim is usually employed by people who are conversant in Linux because it can have an uphill learning curve.

You can use Vim to edit, write, and save a document from the instruction. It does this through the utilization of two different modes:

  • Command
  • Insert

By default, the vim editor opens in command mode. To open the vim editor, use the following syntax at the command line:

$ vim (name of the file)

or

$ vim (full path of the file)

To start writing or editing, you want to enter insert mode by pressing the letter i on your keyboard (“I” for insert). You ought to see —INSERT— at rock bottom of your terminal page if you probably did it correctly.

When you are finished typing and want to save lots of your work, you would like to exit insert mode. Press the escape (ESC) key, which places you back in command mode. Then you’ll save your work.

After you press escape, press shift +; rock bottom of your terminal screen changes to reflect that you did it correctly, you now see a: where the —INSERT— was.

After you see the: within the lower left-hand corner of your vim editor, type w then press enter to save lots of your work. Then, you’ll type I again to travel back to insert mode if you would like to continue writing. Otherwise, you can quit the File. To quit, press shift +; again, type q, then press enter. This protects your File and closes Vim. Finally, you ought to see your usual terminal screen again.

You can also enter both the save and quit functions at an equivalent time. to save lots of and quit Vim in one command, type wq after the: then press enter. The File saves and closes.

If you begin performing on a file but you modify your mind, you’ll exit without saving. to try to to this, enter command mode by pressing ESC followed by shift +; After you see the: at the lower left, enter q!. This force-quits Vim without saving. ! is that the force function.

Those commands are those that you simply are going to use most of the time, but you’ll use the subsequent cheat sheet if you would like to try to to more complex actions with Vim.

  • h – Moves the cursor to the left by one character; you’ll also press the left arrow.

  • a – Appends to the proper of the present cursor position.
  • dw – Deletes the present word.
  • cw – Changes the present word.

Nano

Nano may be a newer text editor in Linux systems. It’s simpler and easier to use than Vim.

To open a file with nano, use the following syntax at the command line:

$ nano (name of the file)

or

$ nano (full path of the file)

After the nano editor opens, you’ll begin typing when you’re able to save your work, press ctrl + o, which is named a write out. It saves your current work while allowing you to continue your work. If you’re done, you’ll save and quit by pressing ctrl + x. once you save an enter nano, your current work is colour-coded, supported by what you’re writing.

  • ^G – Get Help.
  • ^X – Exit. Nano then asks if you would like to save lots with a Y or N option.
  • ^O – Write Out; also referred to as save.

  • ^J – Justify.
  • ^T – To spell.
  • ^C – Current Position; Cancel Save.
  • ^_ – attend line.

linux command line text editor with syntax highlighting

Syntax highlighting may be a simple but useful component in most text editors used for programming, scripting, or markup languages, which enables displaying coloured text, notably ASCII text files, in several colours (and possibly fonts) like the category of terms.

VIM is an alternate and advanced version of VI editor that permits Syntax highlighting feature in VI. Syntax highlighting means it can show some parts of text in other fonts and colours. VIM doesn’t show the whole File but has limitations in highlighting particular keywords or text matching a pattern during a file. By default, VIM works on all Linux terminals, but some have minimal highlighting capabilities to run.

VIM has another great feature that enable us to show Off or activate Syntax highlighting using option syntax on and Syntax off.

How to Install VIM

Most Linux systems already included the VIM package; if not, then install it using the YUM tool.

# yum -y install vim-enhanced

How to Enable Syntax Highlighting in VI and VIM

To enable the Syntax Highlighting feature in VI editor, open the File called /etc/profile.

# vi /etc/profile

Add the alias function to VI by pointing to VIM in the/etc/profile file. This File is employed to line alias functions globally.

alias vi=vim

If you wish to set user-specific aliases and functions, you would like to open the File .bashrc under the user directory.

# vi /home/tecmint/.bashrc

Add the alias function. For instance, we set an alias for the tecmint user.

alias vi=vim

After making the file changes, you would like to reset the changes by executing the following command.

# source /etc/profile
OR
# source /home/tecmint/.bashrc

Test Syntax Highlighting in Vi Editor

Open any example code of File with vi editors. By default, Syntax Highlighting is automatically turned on in the/etc/vimrc File.

Turn On or Turn Off Syntax Highlighting in VI

You can activate or close up Syntax highlighting by pressing the ESC button and use the command: Syntax on and: Syntax off in Vi editor.

Turn on color syntax highlighting in vim

Open a file, for instance open existing file called file.c, enter:

$ vi file.c

Now press ESC key, type “: syntax on” i.e. type as follows:

:syntax on

Turn off color syntax highlighting in vim

To turn it backtrack, press the ESC key, type: Syntax off

:syntax off

How do I make the syntax highlighting permanent under vim?

You can edit the ~/.vimrc file and add append vim command syntax to that. This ensures that Vim will start with a colour syntax highlighting option:

$ cd ~
$ vi .vimrc

Append the subsequent line:

syntax on

Save and shut the File. You ought to now be ready to use Vim to edit files with Syntax on options.

How to set and use a vim color scheme

Use the ls command to list it:

$ ls -l /usr/share/vim/vim*/colors/
