I see no mention of this is the man page for tput ( ncurses version 5.6.20071124 ) on my Ubuntu system. What version of tput are you using?

Code:
$ tput -V
ncurses 5.5.20060422
Nor do I have any mention of "os" or "overstrike" in my tput man page.

However, "overstrike" usually means to print a 2nd character on top another, creating something not in the character set, e.g.: o, |, or _.

Post "os" with tput

"os" is a boolean value which tells an application whether
a terminal can do overstriking. "tput os" would make tput
recognize that it's a boolean, and set tput's exit-code to
0 or 1 (all of which is documented in the terminfo and tput
manpages).

"os", "over_strike", is NOT mentioned in the tput man page you linked to, but rather in the one for terminfo. One has to read both man pages side by side to understand what
Code:
tput os
means/does.

From the terminfo man page:
Quote:
over_strike os os terminal can over-strike

As to the original Q, see the WikipediaŽ overstrike page.

I was responding to the question by davender84 (use of os with tput).
By the way, Wikipedia is not a reliable source of information.
The topic which you have pointed to does in fact need work, since
(a) it contains no references, and
(b) contains some personal opinion in lieu of facts.
