more
From NetBSD Wiki
The more(1) command is the canonical pager (see pagers). It has very little functionality generally. For a pager with more functionality than more, see less.
More simply shows the user a page full of text (by default reading from stdin) and waits for a keypress. When the user presses the spacebar, it will scroll down exactly one page and show the next. If the user presses the enter/return key, it will scroll only by one line. More quits by default when it hits end of file.
