- General Options + These are hardware tabs, which cannot be queried rapidly by applica- + tions running in the terminal, if at all. Curses and other full-screen + applications may use hardware tabs in optimizing their output to the + terminal. If the hardware tabstops differ from the information in the + terminal database, the result is unpredictable. + + +

-Tname - Tell tabs which terminal type to use. If this option - is not given, tabs will use the $TERM environment - variable. If that is not set, it will use the - ansi+tabs entry. - - -d The debugging option shows a ruler line, followed by - two data lines. The first data line shows the - expected tab-stops marked with asterisks. The second - data line shows the actual tab-stops, marked with - asterisks. - - -n This option tells tabs to check the options and run - any debugging option, but not to modify the terminal - settings. - - -V reports the version of ncurses which was used in this - program, and exits. - - The tabs program processes a single list of tab stops. - The last option to be processed which defines a list is - the one that determines the list to be processed. - - Implicit Lists - Use a single number as an option, e.g., "-5" to set tabs - at the given interval (in this case 1, 6, 11, 16, 21, - etc.).
