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. Some, but not all, pagers allow movement up a file.[1] A popular cross-platform terminal pager is more, which can move forwards and backwards in text files but cannot move backwards in pipes.[2] less is a more advanced pager that allows movement forward and backward, and contains extra functions such as search.[3]
Some programs incorporate their own paging function, for example bash's tab completion function.[4]
