.Op Fl dlfpcsu
.Op Fl num
.Op +/ pattern
.Op + linenum
.Op Ar
.Sh DESCRIPTION
.Nm More
is a filter for paging through text one screenful at a time.  This version
is especially primitve.  Users should realize that
.Xr less 1
provides
.Xr more 1
emulation and extensive enhancements.
.Sh OPTIONS

will prompt the user with the message "[Press space to continue, 'q' to
quit.]" and will display "[Press 'h' for instructions.]" instead of ringing
the bell when an illegal key is pressed.
.It Fl l
.Nm more
usually treats
.Ic \&^L
(form feed) as a special character, and will pause after any line that
contains a form feed.  The
.Fl l
option will prevent this behavior.
.It Fl f
Causes
.Nm more
to count logical, rather than screen lines (i.e., long lines are not
folded).
.It Fl p
Do not scroll.  Instead, clear the whole screen and then display the text.
.It Fl c
Do not scroll.  Instead, paint each screen from the top, clearing the
remainder of each line as it is displayed.
.It Fl s
Squeeze multiple blank lines into one.
.It Fl u
Suppress underlining.
.It Ic +/
The
.Ic +/
option specifies a string that will be searched for before
each file is displayed.
.It Ic +num
Start at line number
.Ic num .
