more

Display output one screen at a time, less provides more emulation and extensive enhancements.

Syntax
      more [-dlfpcsu] [-num] [+/ pattern] [+ linenum] [file ...]

Options
     Command line options are described below.  Options are also taken from
     the environment variable MORE (make sure to precede them with a dash
     (''-'')) but command line options will override them.
 
     -num  This option specifies an integer which is the screen size (in
           lines).
 
     -d    more 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.
 
     -l    more usually treats ^L (form feed) as a special character, and will
           pause after any line that contains a form feed.  The -l option will
           prevent this behavior.
 
     -f    Causes more to count logical, rather than screen lines (i.e., long
           lines are not folded).
 
     -p    Do not scroll.  Instead, clear the whole screen and then display
           the text.             
     -c    Do not scroll.  Instead, paint each screen from the top, clearing
           the remainder of each line as it is displayed.
 
     -s    Squeeze multiple blank lines into one.
 
     -u    Suppress underlining.
 
     +/    The +/ option specifies a string that will be searched for before
           each file is displayed.
 
     +num  Start at line number num.
