  46. .Sh DESCRIPTION
  47. The
  48. .Nm
  49. utility displays a series of characters that first clears the hardware terminal
  50. tab settings and then initializes the tab stops at the specified positions
  51. and optionally adjusts the margin.
  52. .Pp
  53. The phrase "tab-stop position N" means that, from the start of a line of
  54. output, tabbing to position N shall cause the next character output to be in
  55. the (N+1)th column on that line.
  56. .Pp
  57. The following options are supported:
  58. .Bl -tag -width Fl
  59. .It Fl Ar n
  60. Specifies repetitive tab stops separated by a uniform number of columns,
  61. .Ar n ,
  62. where
  63. .Ar n
  64. is a single digit decimal number.
  65. The default usage of
  66. .Nm
  67. with no arguments is equivalent to
  68. .Nm
  69. .Fl 8 .
  70. When
  71. .Fl 0
  72. is used, the tab stops are cleared and no new ones set.
  73. .It Fl a

  126. The

  128. and
  129. .Ev TERM
  130. environment variables affect the execution of
  131. .Nm
  132. as described in
  133. .Xr environ 7 .
  134. .Pp
  135. The
  136. .Fl T
  137. option overrides
  138. .Ev TERM .
  139. If neither
  140. .Ev TERM
  141. nor the
  142. .Fl T
  143. option are present,
  144. .Nm
  145. will fail.
