.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility displays a series of characters that first clears the hardware terminal
|
|
tab settings and then initializes the tab stops at the specified positions
|
|
and optionally adjusts the margin.
|
|
.Pp
|
|
The phrase "tab-stop position N" means that, from the start of a line of
|
|
output, tabbing to position N shall cause the next character output to be in
|
|
the (N+1)th column on that line.
|
|
.Pp
|
|
The following options are supported:
|
|
.Bl -tag -width Fl
|
|
.It Fl Ar n
|
|
Specifies repetitive tab stops separated by a uniform number of columns,
|
|
.Ar n ,
|
|
where
|
|
.Ar n
|
|
is a single digit decimal number.
|
|
The default usage of
|
|
.Nm
|
|
with no arguments is equivalent to
|
|
.Nm
|
|
.Fl 8 .
|
|
When
|
|
.Fl 0
|
|
is used, the tab stops are cleared and no new ones set.
|

.Sh ENVIRONMENT
|
|
The

.Ev COLUMNS
|
|
and
|
|
.Ev TERM
|
|
environment variables affect the execution of
|
|
.Nm
|
|
as described in
|
|
.Xr environ 7 .
|
|
.Pp
|
|
The
|
|
.Fl T
|
|
option overrides
|
|
.Ev TERM .
|
|
If neither
|
|
.Ev TERM
|
|
nor the
|
|
.Fl T
|
|
option are present,
|
|
.Nm
|
|
will fail.
