Dear lynx experts:
I am invoking the following command from a PPP script:
lynx -auth=${ID}:${PASSWD} -source -post_data ${URL}
where URL is of the form <http address>/<x-www-url-encoded post data>
I am having two problems:
* Since PPP has all file descriptors set to null, and I think that
is what is causing the following error message:
Your terminal lacks the ability to clear the screen or position
the cursor.
Lynx then quits. When I run the script manually, everything works
fine. How can disable lynx's efforts to manipulate the
(non-existant?) terminal? Is lynx not the right program to use for
my purpose? I tried wget, but I couldn't get it to "POST" anything
...
* As the reader can see, my auth info is on the command line.
While I am essentially the only user on my system, and the command
is only alive for a few moments, the given invocation is still
undesirable from a security standpoint. I tried feeding the options
and post data through STDIN, but lynx hangs because it does not
receive an EOT (control-d) character. How can I a, say, "echo" an
EOT character? Is there an ASCII code for it? Should I feed the
post data into a temp file, then 'cat' it?
I do not subscribe to the list, so CCs to my personal address
(address@hidden) would be appreciated. I apologize if these issues
have been addressed before, but I could not find a solution in the
archives.
Thank you.
Regards,
Sourav Mandal
