How to use Shell Functions In Linux
To simplify the process of printing colored text, you can define shell functions in your scripts. Here’s an example of a shell function for printing colored text:
We’ll create a script using vim editor
vim color
#!/bin/bash
print_color() {
local color=$1
local text=$2
echo -e “$(tput setaf $color)$text$(tput sgr0)”
}# Usage
print_color 2 “This text is green”
Executing Script
bash color
This function takes two arguments: the color code and the text to be printed. It then applies the specified color to the text using tput.
How to Print Colored Text to the Linux Terminal
Printing colored text to the Linux terminal can greatly enhance the visual appeal and readability of your command-line applications or scripts. While the terminal traditionally displays text in monochrome, incorporating colors can provide crucial context, highlight important information, or simply add a touch of aesthetic appeal. In this comprehensive guide, we will explore various methods to print colored text to the Linux terminal, covering everything from basic ANSI escape sequences to more advanced techniques using libraries like tput and terminfo.
