TABS(1)			FreeBSD	General	Commands Manual		       TABS(1)

NAME
     tabs -- set terminal tabs

SYNOPSIS
     tabs [-n |	-a | -a2 | -c |	-c2 | -c3 | -f | -p | -s | -u] [+m[n]]
	  [-T type]
     tabs [-T type] [+[n]] n1[,n2,...]

DESCRIPTION
     The tabs utility displays a series	of characters that clear the hardware
     terminal tab settings then	initialises tab	stops at specified positions,
     and optionally adjusts the	margin.

     In	the first synopsis form, the tab stops set depend on the command line
     options used, and may be one of the predefined formats or at regular
     intervals.

     In	the second synopsis form, tab stops are	set at positions n1, n2, etc.
     If	a position is preceded by a `+', it is relative	to the previous	posi-
     tion set.	No more	than 20	positions may be specified.

     If	no tab stops are specified, the	``standard'' UNIX tab width of 8 is
     used.

     The options are as	follows:

     -n	     Set a tab stop every n columns.  If n is 0, the tab stops are
	     cleared but no new	ones are set.

     -a	     Assembler format (columns 1, 10, 16, 36, 72).

     -a2     Assembler format (columns 1, 10, 16, 40, 72).

     -c	     COBOL normal format (columns 1, 8,	12, 16,	20, 55)

     -c2     COBOL compact format (columns 1, 6, 10, 14, 49)

     -c3     COBOL compact format (columns 1, 6, 10, 14, 18, 22, 26, 30, 34,
	     38, 42, 46, 50, 54, 58, 62, 67).

     -f	     FORTRAN format (columns 1,	7, 11, 15, 19, 23).

     -p	     PL/1 format (columns 1, 5,	9, 13, 17, 21, 25, 29, 33, 37, 41, 45,
	     49, 53, 57, 61).

     -s	     SNOBOL format (columns 1, 10, 55).

     -u	     Assembler format (columns 1, 12, 20, 44).

     +m[n], +[n]
	     Set an n character	left margin, or	10 if n	is omitted.

     -T	type
	     Output escape sequence for	the terminal type type.

ENVIRONMENT
     The LANG, LC_ALL, LC_CTYPE	and TERM environment variables affect the exe-
     cution of tabs as described in environ(7).

     The -T option overrides the setting of the	TERM environment variable.  If
     neither TERM nor the -T option are	present, tabs will fail.

EXIT STATUS
     The tabs utility exits 0 on success, and >0 if an error occurs.

SEE ALSO
     expand(1),	stty(1), tput(1), unexpand(1), termcap(5)

STANDARDS
     The tabs utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'').

HISTORY
     A tabs utility appeared in	PWB UNIX.  This	implementation was introduced
     in	FreeBSD	5.0.

BUGS
     The current termcap(5) database does not define the `ML' (set left	soft
     margin) capability	for any	terminals.
