Pipes
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
scripts/
script.sh
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.
