  50        <STRONG>tabs</STRONG> - set tabs on a terminal
  51
  52
  53 </PRE>
  54 <H2>SYNOPSIS</H2><PRE>
  55        <STRONG>tabs</STRONG> [<STRONG>-v</STRONG>[<EM>n</EM>]] [<STRONG>-ahuUV</STRONG>] <EM>file...</EM>

  59 <H2>DESCRIPTION</H2><PRE>
  60        The  <STRONG>tabs</STRONG>  program clears and sets tab-stops on the termi-
  61        nal.  This uses the terminfo  <EM>clear</EM><STRONG>_</STRONG><EM>all</EM><STRONG>_</STRONG><EM>tabs</EM>  and  <EM>set</EM><STRONG>_</STRONG><EM>tab</EM>
  62        capabilities.   If  either  is  absent,  <STRONG>tabs</STRONG> is unable to
  63        clear/set tab-stops.  The terminal should be configured to
  64        use hard tabs, e.g.,
  65
  66               stty tab0
  67

  70 <H2>OPTIONS</H2><PRE>
  71    <STRONG>General</STRONG> <STRONG>Options</STRONG>
  72        <STRONG>-T</STRONG><EM>name</EM>
  73             Tell <STRONG>tabs</STRONG> which terminal type to use.  If this option
  74             is not given, <STRONG>tabs</STRONG> will  use  the  <STRONG>$TERM</STRONG>  environment
  75             variable.   If  that  is  not  set,  it  will use the
  76             <EM>ansi+tabs</EM> entry.
  77
  78        <STRONG>-d</STRONG>   The debugging option shows a ruler line, followed  by
  79             two  data  lines.   The  first  data  line  shows the
  80             expected tab-stops marked with asterisks.  The second
  81             data  line  shows  the  actual tab-stops, marked with
  82             asterisks.
  83
  84        <STRONG>-n</STRONG>   This option tells <STRONG>tabs</STRONG> to check the options  and  run
  85             any  debugging option, but not to modify the terminal
  86             settings.
  87
  88        The <STRONG>tabs</STRONG> program processes a single  list  of  tab  stops.
  89        The  last  option  to be processed which defines a list is
  90        the one that determines the list to be processed.
  91
  92    <STRONG>Implicit</STRONG> <STRONG>Lists</STRONG>
  93        Use a single number as an option, e.g., "<STRONG>-5</STRONG>" to  set  tabs
  94        at  the  given  interval  (in  this case 1, 6, 11, 16, 21,
  95        etc.).  Tabs are repeated up to the right  margin  of  the
  96        screen.
  97
  98        Use "<STRONG>-0</STRONG>" to clear all tabs.
  99
 100        Use "<STRONG>-8</STRONG>" to set tabs to the standard interval.
 101
 102    <STRONG>Explicit</STRONG> <STRONG>Lists</STRONG>
 103        An  explicit  list  can be defined after the options (this
 104        does not use a "-").  The values in the list  must  be  in
 105        increasing numeric order, and greater than zero.  They are
 106        separated by a comma or a blank, for example,
 107
 108               tabs 1,6,11,16,21
 109               tabs 1 6 11 16 21
 110        Use a '+' to treat a number as an  increment  relative  to
 111        the previous value, e.g.,
 112
 113               tabs 1,+5,+5,+5,+5
 114        which is equivalent to the 1,6,11,16,21 example.
 115
 116    <STRONG>Predefined</STRONG> <STRONG>Tab-Stops</STRONG>
 117        X/Open defines several predefined lists of tab stops.

 139 <H2>PORTABILITY</H2><PRE>
 140        X/Open  describes  a  <STRONG>+m</STRONG> option, to set a terminal's left-
 141        margin.  Very few of the entries in the terminal  database
 142        provide this capability.
 143
 144        The  <STRONG>-d</STRONG>  (debug) and <STRONG>-n</STRONG> (no-op) options are extensions not
 145        provided by other implementations.
 146
 147        Documentation for other implementations states that  there
 148        is  a limit on the number of tab stops.  While some termi-
 149        nals may not accept an arbitrary number of tab stops, this
 150        implementation  will  attempt  to  set tab stops up to the
 151        right margin of the screen, if the given list  happens  to
 152        be that long.
