SYNOPSIS

       tabs [tabspec] [+mn] [-Ttype]

DESCRIPTION

       Tabs  sets the tabs on a variety of terminals, according to tabspec; if
       no such argument is present, the default is -8 (set tabulator stops  at
       every eight positions).

       The tabspec argument can be one of the following:

       -n     Set  a  tab  stop at every n positions. If n is 0, all tab stops
              are cleared and no new ones are set.

       n1,n2, . . .
              Set a tab stop at n1, n2, and any following numbers.   A  number
              prefixed  by  a  plus sign is interpreted as an increment to the
              previous position.

       -a     1,10,16,36,72; IBM System/370 Assembler, first format.

       -a2    1,10,16,40,72; IBM System/370 Assembler, second format.

       -c     1,8,12,16,20,55; COBOL, normal format.

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

       -c3    1,6,10,14,18,22,26,30,34,38,42,46,50,54,58,62,67; COBOL  compact
              format with additional tabs.

       -f     1,7,11,15,19,23; FORTRAN format.

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

       -s     1,10,55; SNOBOL format.

       -u     1,12,20,44; UNIVAC 1100 Assembler format.

       --file Read  the  tabulator  specifications from the first line of file
              (if file is omitted, read from standard  input).   See  fspec(5)
              for the format of the tabulator specification line.

       Other arguments are:

       -Ttype Overrides  the  default  terminal type.  Various of the terminal
              names given in term(7) are recognized.


       +mn    Sets the left margin to n or, if n is omitted, to 10  (if
              supported  by  the terminal).  The leftmost margin can be
              set with +m0.  The left margin is  not  set  unless  this
              argument is present.
