-num lines: Sets the number of lines that make up a screenful. The lines must be an integer.
-d: With this option, more will prompt the user with the message “[Press space to continue, ‘q' to quit.]” and display “[Press ‘h' for instructions.]” when an illegal key is pressed, instead of ringing a bell.
-l: more usually treats ^L (CONTROL-L, the form feed) as a special character, and will pause after any line that contains it. The -l option will prevent this behavior.

-p: Do not scroll. Instead, clear the whole screen and then display the text. This option is switched on automatically if the more executable is named page.
