Ever run a command, like the dir command, that produces so much information on the screen that it's almost useless?
One way to manage this info dump is to execute the command in a special way so whatever information is generated is shown to you one page, or one line, at a time.
Just type the command, the dir command for example, and then follow it with the pipe character and then the more command.
For example, executing dir /s | more will generate the thousands of lines of results that you expect from the dir command, but the more command will pause each page of results with -- More -- at the bottom of the page, indicating that the command is not done running.
Just press the spacebar to advance by page or press Enter to advance one line at a time.
