HON: Faculty Notes to Chapter 3
Home > Faculty > Chapter Notes > Chapter 3
Chapter 3
Chapter 3 in the second edition
of Hands-On
contains three new experiments which involve
writing scripts.
That raises the question of which shell to use,
and the most important answer seems to be, "Not
bash". Scripting is not my strong suit,
but with help from colleagues, the internet, and students
(Matt Post in particular) I
came up with this solution (using the fortune cookie
experiment for illustration):
|
#!/bin/sh
|
tpipe() {
|
sleep 3;echo 1; sleep 1; echo 10
|
}
|
tpipe | telnet cookie.update.uu.se 8445 2>/dev/null | sed '/Trying/d;/Connect/d;/Escape/d;/Connection/d;'
