1/28    Are there any unix-based scripts that will periodically check a
        webpage to see if it has changed?  I know such a tool is not that
        complex to write, but why reinvent the wheel?  Thanks.
        \_ some hints:  lynx > out.  diff.  cron.  notify (email probably).
        \_ I think that you can have curl and wget send an IMS header.
           \_ Damn... stop with the curl thing.  You don't need to install and
              learn yet-another-scripting-language to do something this
              trivial.  Curl is not going to change the universe.
              \_ Are you confusing curl the unix utility with curl the
                 stupid scripting language from MIT?
              \_ curl is a little pgm like wget that is installed on
                 most BSD systems as part of the base or via the ports.
                 My experience is that it is easier to get curl to send
                 arbitrary headers than with wget.
                 I don't know where you got this scripting language thing
                 from.
                 \_ Oh you're right.  My bad.  Yes, I thought you were talking
                    about the new 'kewl' scripting language from MIT.
        \_ if this is for a personal use check <DEAD>netmind.com<DEAD>
        \_ There's an HTTP header specifically for this ("If-Modified-Since").
           It'd take less time to write the script than to ask.

        \_ Larry Ellison is a secret Tea Party supporter.
           Most of this article is bunk, btw. Boy are the Republicans
           getting desperate.
            \_ Umm, no.  Larry Ellison is a not so secret fascist.
