.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
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.
|
|
.Pp
|
|
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.
|
|
.Pp
|
|
In the second synopsis form, tab stops are set at positions
|
|
.Ar n1 , n2 ,
|
|
etc.
|
|
If a position is preceded by a
|
|
.Ql + ,
|
|
it is relative to the previous position set.
|
|
No more than 20 positions may be specified.
|
|
.Pp
|
|
If no tab stops are specified, the
|
|
.Dq standard
|
|
.Ux
|
|
tab width of 8 is used.
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width indent
|
|
.It Fl Ar n
|
|
Set a tab stop every
|
|
.Ar n

|
|
If
|
|
.Ar n
|
|
is 0, the tab stops are cleared but no new ones are set.

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