What are the diffrences between `tput cols`, `tput lines` and `stty size`?

Question

Are there differences between tput cols, tput lines and stty size written in this way (apart that stty size returns all in one string)?

Is one more portable or more reliable than the other?

Answer 1

At the moment I am asking myself the same question.

What I see on linux:

• tput depends on ncurses
• stty depends on coreutils and coreutils depends on ncurses

IMHO tput is more basic and portable.
