Using pipes allows you to alter accepted input, accepted output, and accepted error.
Suppose you wish to save the achievement of a program to a file. You would use > as an abettor to alter that achievement to a file. For instance, the afterward would yield the aftereffect of man gcc, and save the argument that would accept been displayed on the awning into a book alleged blah.txt
man gcc > blah.txt
Suppose instead, you capital to be able to annal up and down the achievement of man gcc, instead of accepting it all displayed to the awning at once. You could use | to aqueduct the accepted achievement of one command to the accepted ascribe of another. The afterward outputs a book to accepted output, but then redirects that to a argument viewer.
cat blah.txt | less
Suppose you wish to simulate a affair with a command band interface by using a collapsed book instead of accepting a user collaborate with the program. You can use < to specify accepted input. The afterward uses input.txt as the ascribe for the java program.
java myProgram < input.txt
