ANSI Escape Codes
Understanding ANSI Escape Codes for Terminal Formatting
ANSI escape codes are a standard for controlling text formatting and cursor position in text terminals. They allow you to add color, style (like bold or underline), and even control the cursor's movement, making your command-line output more readable and visually appealing. This tool provides a comprehensive list of common ANSI escape codes for various formatting options.
Common ANSI Escape Code Categories
Text Formatting Codes
These codes modify the appearance of the text itself, such as its color or boldness.
Background Color Codes
These codes set the background color behind the text.
Style and Intensity Codes
These codes apply styles like underline or high intensity to the text.
Reset Code
The reset code is crucial for returning the terminal to its default state after applying formatting.

How to Use ANSI Escape Codes
To use these codes in your shell scripts or applications, you typically embed them within strings. For example, to print "Hello, World!" in red, you would use something like:
echo -e "\e[31mHello, World!\e[0m"
The -e
flag for the echo
command enables the interpretation of backslash escapes. The \e[31m
sets the color to red, and \e[0m
resets it. Experiment with different codes to create vibrant and informative terminal outputs.
