A terminal pager, paging program or simply pager is a computer program used to view (but not modify) the contents of a text file moving down the file one line or one screen at a time.

most (Unix) most is a terminal pager program on Unix, OpenVMS, MS-DOS, Windows [1] and Unix-like systems used to view (but not change) the contents of a text file one screen at a time. Programs of this sort are called pagers. [2] It is similar to more, but has the extended capability of allowing both forward and backward navigation through the ...
