[ale] Fwd: Re: [ale] i just don't "get" it yet GOT IT

[Charles Shapiro]

I've had good luck using expect(1) for things like this. I'm not sure it
is installed by default on your distro, but the rpm is on the
distributed RedHat CD at least as far back as 6.2. The Debian Potato
distro also carries a .deb file which you can install with dselect. It's
a full-fledged programming language written to control things like
telnet(1), ftp(1), and other stuff where you need to simulate a user
sitting at a keyboard. For example, I ssh(1) to developmment boxen here
from an icon on my desktop with the script:

#!/usr/bin/expect

spawn ssh -l cshapiro $argv
expect "password:"
send "my_secret_password_which_isnt_this\r"
interact

So for your automated thing it'd be something like

#!/usr/bin/expect
spawn ftp remote.system

expect "ername:"
send "username\r"
expect "ssword:"
send "password\r"
send "get /home/rk4com/CLbackup.tgz /data/foo\r"
expect "226"

et cetera and so forth. Expect has all kinds of timeout and error
checking stuff which I haven't put into this example; you can, of
course, make your script as complex and wonderful (or simple and robust)
as you wish.
