Help with a unix shell script plz

Repli

Hi guys,

Im writing a shell script that telnets to websites on port 80 and then issues GET requests and pipes the output back to a file. Something like

telnet www.bla.com 80
GET /folder/indexFile.php

however I cant put GET requests on a line on their own in the shell script because it isn't a unix command?

Any help appreciated - thanks

Is there any reason not to use wget (or similar)? Seems like it would be a easier solution, though it does assume the presence of something like wget in the first place.

Thank you, will give that a try now

you could use expect
handy fer interactive stuffs ...
telnet blah
expect 'output'
send blah
expect 'more stuff'
send more

and so on...

GET /folder/indexFile.php; | telnet www.bla.com 80

might work perhaps?

Could try..

(sleep 3; echo username; sleep 3; echo password; sleep 5; echo "GET /folder/indexFile.php"; sleep 3; echo "exit") | telnet www.bla.com 80

take out username and password if not required and adjust sleep if required

Hi,
wget is probably your best answer for this, and expect/autoexpect are designed to help you automate this kind of interaction.
Try: autoexpect telnet www.bla.com 80 and see what happens.
You'll need to go through the script afterwards to remove timestamps and other things that will be different session to session.


To answer your problem of not being able to put GET
on a line on it's own, the construction you need is
called a 'here file'. It would look as follows:

telnet www.bla.com 80 <<EOF
GET /folder/indexFile.php
EOF

This starts the command and feeds it everything it reads line by line
until it reads EOF.

I still think wget is your best bet in this situation,
but this is worth knowing.

Or just use curl.

Use curl or wget or something. The above wouldn't work for virtal-hosted sites or sites that are fussy about HTTP syntax, anyway.
