Using Command-Line Tools to View Text Files

Linux offers several powerful command-line utilities for opening and viewing text files efficiently. These tools are especially useful when working on servers or systems without graphical interfaces.

The `cat` command is one of the simplest ways to display the entire contents of a text file directly in the terminal. It is ideal for small files but may become unwieldy with large files since it outputs everything at once.

“`bash
cat filename.txt
“`

For larger files, utilities like `less` and `more` allow for paginated viewing, enabling users to scroll through the content conveniently.

  • `less`: Provides forward and backward navigation, searching, and more advanced features.
  • `more`: Allows forward navigation page by page but is more limited than `less`.

Example usage:

“`bash
less filename.txt
“`

or

“`bash
more filename.txt
“`

To view only the beginning or the end of a file, `head` and `tail` commands are useful:

  • `head`: Displays the first 10 lines by default.
  • `tail`: Displays the last 10 lines by default.

You can specify the number of lines to view with the `-n` option:

“`bash
head -n 20 filename.txt
tail -n 15 filename.txt
“`

These commands are valuable for quickly inspecting logs or files without opening the entire content.

Editing Text Files via Terminal

Beyond viewing, Linux provides several text editors that can be used directly from the terminal to open and modify `.txt` files. These editors range from simple to highly feature-rich environments.

  • `nano`: A user-friendly text editor with straightforward commands displayed at the bottom of the screen. Ideal for beginners.
  • `vim`: A powerful and highly configurable editor favored by many advanced users. It has a steeper learning curve but offers extensive functionality.
  • `emacs`: Another powerful editor with a rich set of features and extensibility.

To open and edit a file with `nano`, use:

“`bash
nano filename.txt
“`

For `vim`, the command is:

“`bash
vim filename.txt
“`

Each editor has its own set of commands for saving, exiting, and editing. For example, in `nano`, saving is done with `Ctrl + O` and exiting with `Ctrl + X`. In `vim`, entering command mode by pressing `Esc` and typing `:wq` saves and quits the editor.

Graphical Applications for Viewing and Editing Text Files

If you are working in a Linux environment with a graphical user interface (GUI), several applications can open and edit text files with ease.

Common GUI text editors include:

  • Gedit: The default GNOME text editor, simple and easy to use.
  • Kate: The KDE text editor with advanced features.
  • Mousepad: Lightweight editor often used in XFCE environments.
  • Leafpad: Minimalist and fast editor.

To open a text file with Gedit, use the command:

“`bash
gedit filename.txt &
“`

The ampersand (`&`) runs the program in the background, allowing you to continue using the terminal.

Alternatively, you can open these applications through the system menu or by right-clicking the text file and selecting the appropriate editor.
