How to change the output color of echo in Linux

Question

I am trying to print a text in the terminal using echo command.

I want to print the text in a red color. How can I do that?

Answer 1

I've written swag to achieve just that.

You can just do

pip install swag

Now you can install all the escape commands as txt files to a given destination via:

swag install -d 

Or even easier via:

swag install

Which will install the colors to ~/.colors.

Either you use them like this:

echo $(cat ~/.colors/blue.txt) This will be blue

Or this way, which I find actually more interesting:

swag print -c red -t underline "I will turn red and be underlined"
