i am using rhel-5 and ncurses-5.5-24.20060715 os=overstrike "os" is a boolean capability used with tput command i want to know the use of "os" with tput |
Code:
$ tput -V However, "overstrike" usually means to print a 2nd character on top another, creating something not in the character set, e.g.: o, |, or _. |
"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 From the terminfo man page: Quote:
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. hth |
thanks to u
