Question

I’ve a text file with a line

default_color acolor

and I want to replace this line with

default_color anothercolor

I don’t know the first color and the second is contained in a variable.
How can I do it in bash ?

It is not pure bash but if you have other console tools, try something like

cat your_file | sed "s/default_color\ .*/default_color\ $VAR/"
