This is the command tabs that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
NAME
tabs - set tabs on a terminal
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 example,
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.,
tabs 1,+5,+5,+5,+5
which is equivalent to the 1,6,11,16,21 example.
Predefined Tab-Stops
X/Open defines several predefined lists of tab stops.
-a Assembler, IBM S/370, first format
-a2 Assembler, IBM S/370, second format
-c COBOL, normal format
-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 arbitrary 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.
