Pipes are really cool, you can output one command into the input of another using |.

To learn pipes we will learn a new command, grep. grep is used to search for certain strings. Example:

dave@[datadyne]:~/$ ls
bin/      how to raid/  pythonweb/  scripts/   unix/            wireless/
code/     mpd.conf      rotate.sh   script.sh  update.sh        www
file.txt  opt           sabres/     temp/      viridianplayer/
dave@[datadyne]:~/$ ls | grep script

I first ran ls by itself, and then in the second command I piped ls to grep and searched for "script". As you can see there were 2 matches, the directory and the file because they both contain the word "script" in them.
