Using a pipe as a delimiter
It is also not uncommon for one or more pipe characters to be used as a delimiter in a text file because it is not commonly used.
When using the pipe in a command it can be used in MS-DOS, Windows command line, and in the Linux console to display a command or a commands output one page at a time. For example, typing dir | more would display the output of the dir command one page a time.
