Hi 
Pipes  | 

Expects two programs, the first must write standard out, stdout,
the second must read standard in, stdin. Then the command line:

	cat file | less

sends stdout from cat file to a fifo file on the disk which is then
read into stdin for less (and is displayed a page at a time).

Redirect  >

Expects the program to write stdout, and opens a file for writing
(deleting any former contents) and writes the output of the program
	
       ls > filelist

the file, filelist, is opened for writing, any former contents
deleted, and the  directory listing from ls is written on filelist.

Hope this helps.
