tabs


SYNOPSIS
       tabs [options]] [tabstop-list]

DESCRIPTION
       The  tabs program clears and sets tab-stops on the terminal.  This uses
       the terminfo clear_all_tabs and set_tab  capabilities.   If  either  is
       absent,  tabs is unable to clear/set tab-stops.  The terminal should be
       configured to use hard tabs, e.g.,

              stty tab0

OPTIONS
   General Options
       -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.).  Tabs are  repeated  up
       to the right margin of the screen.

       Use "-0" to clear all tabs.

       Use "-8" to set tabs to the standard interval.

   Explicit Lists
       An  explicit list can be defined after the options (this does not use a
       "-").  The values in the list must be in increasing numeric order,  and
       greater than zero.  They are separated by a comma or a blank, for exam-
       ple,

              tabs 1,6,11,16,21
              tabs 1 6 11 16 21
       Use a '+' to treat a number as an increment relative  to  the  previous
       value, e.g.,

       -c2  COBOL compact format

       -c3  COBOL compact format extended

       -f   FORTRAN

       -p   PL/I

       -s   SNOBOL

       -u   UNIVAC 1100 Assembler

PORTABILITY
       X/Open  describes  a  +m option, to set a terminal's left-margin.  Very
       few of the entries in the terminal database provide this capability.

       The -d (debug) and -n (no-op) options are extensions  not  provided  by
       other implementations.

       Documentation for other implementations states that there is a limit on
       the number of tab stops.  While some terminals may not accept an  arbi-
       trary  number of tab stops, this implementation will attempt to set tab
       stops up to the right margin of the screen, if the given  list  happens
       to be that long.
