More (Unix)

more is a Computer program on Unix and Unix-like systems used to view (but not change) the contents of a text Computer file one screen at a time. It is similar to less (Unix), but only allows forward navigation through the file (although newer implementations of more do allow for limited backward movement). The command-syntax is:

more [options]

more can be invoked with options to change its behaviour, for example, the number of lines to display on the screen. These options may vary from one Unix to another. While more is displaying the file, various commands can be used to scroll through the file, for example, the [Return/Enter] key scrolls the file forward one line, while the [Space] key scrolls the file forward one screen. It is also possible to search for character patterns in the file. Refer to the more manual for details.

By default, more displays the contents of the file to the standard output (one screen at a time). If the output is redirected to anything other than a Computer terminal, or Pipeline (Unix) to another command, more behaves like cat (Unix).

more is a standard command in all Unix systems. For those implementations that allow it, more does slow down when moving backwards through large files.
