pg—displays files a page at a time
pg [ –number ] [ –p string ] [ –cefnrs ] [ +linenumber ] [ +/pattern/ ] [ filename … ]
The pg command is a filter that allows you to page through filenames one screenful at a time on a terminal. If no filename is specified or if it encounters the – filename, pg reads from standard input. Each screenful is followed by a prompt. If the user types a RETURN, another page is displayed. It allows you to back up and review something that has already passed. (See "more" on page703).
