How to use tput In Linux
The tput command is a POSIX standard utility that enables terminal-related operations, including setting text attributes and colors. Here’s how you can use tput to print colored text:
Create script using vim editor
vim colorchangingtext
#!/bin/bash
RED=$(tput setaf 1) RESET=$(tput sgr0) echo “${RED}This text is red${RESET}”
Executing Script
bash colorchangingtext
In this example:
- tput setaf 1 sets the foreground color to red.
- tput sgr0 resets text formatting.
You can replace 1 with other color codes as per the tput documentation.
