Folks,

I created a script that retrieves a result from a specific website. This site requires authentication, so I am using lynx with its scripting funcionality (cmd_log / cmd_script parameters). The Lynx automated script itself saves the result page into a file, so it's not necessary to use dump or any sort of redirection of standard output to a file.

Here is the main line:

lynx -cmd_script=/path/thescript.lynx theurl 1>> /dev/null

The script works fine. But when I run the script through another server via SSH (ssh -x -q user@server "/path/script.sh") the script hangs in the lynx line. Something is wrong with the lynx automation... I tried to use -dump, it worked fine (it dumped the authentication page, of course).

Any clue?

Does the script exist on the remote server?

If so, you might try opening an ssh session on the remote server and executing the script directly.

Also, remove the "-q" option so you can see if ssh is responding with information on a problem.

I thought: "Humm, it must be something related to the standard input".

This is the stupidest workaround EVER. It worked!

echo "" | lynx -cmd_script=/path/thescript.lynx theurl 1>> /dev/null

Why do you use >>/dev/null instead of >/dev/null. That might cause a hang.
