Draw a horizontal line from dash character occupying the full width of a terminal in bash

Question

I need a command that will draw a horizontal "line" in the terminal. The line must be exactly the width of the terminal long (regardless of a current terminal width) and consist of a dash character (although a unicode symbol for a horizontal line can be also used).

It is better if it can be colored.

I need to use it like this:

echo some text
drawline
echo more text

And the output would look something like this:

echo some text
---------------------------------------------------------------------------------
echo more text

Answer 1

Try with:

echo some text
printf '%*s\n' "${COLUMNS:-$(tput cols)}" '' | tr ' ' -
echo some text
