.Nm
.Op Fl bs

.Sh DESCRIPTION
The

breaking the lines to have a maximum of 80 columns.
.Pp
The options are as follows:
.Bl -tag -width indent
.It Fl b
Count
.Ar width
in bytes rather than column positions.
.It Fl s
Fold line after the last blank character within the first
.Ar width
column positions (or bytes).
.It Fl w Ar width
Specify a line width to use instead of the default 80 columns.
The
.Ar width
value
should be a multiple of 8 if tabs are present, or the tabs should
be expanded using
.Xr expand 1
before using
.Nm .
.El
.Sh ENVIRONMENT
The
.Ev LANG , LC_ALL
and
.Ev LC_CTYPE
environment variables affect the execution of
.Nm
as described in
.Xr environ 7 .
.Sh SEE ALSO

.Xr fmt 1
.Sh STANDARDS
The
.Nm
utility conforms to
.St -p1003.1-2001 .
.Sh BUGS
