Basic Bash pipe tricks -



i'm going run short demonstration of linux audience of 9-10 y.o children @ school. guess none has never seen shell, fun of them i'd show how many things can achieve one-liner pipe.
i'd start with:

echo "hello world"

and then:

echo "hello world" | figlet echo "hello world" | rev echo "hello world" | mail johndoe@gmail.com

can suggest me one-liner can use echo ? lot!

if have access netcat (nc) , browser can this:

echo "hello world!" | nc -l localhost 2888

then open browser on http://localhost:2888/ see message.
