get the contents of whole site like some wiki or wikia

For wikis and wikia, generally if you are trying to get some url mirror, then websucker.py is an excellent option. This script is in the python sources so, to get this tool,

yumdownloader --source python

Install the rpm downloaded in current directory and then go to ~/rpmbuild/SOUURCES.  You should find a Python-*.tar.xz file here, just extract with

tar xvf Python*.tar.xz

and there you go, you should find the tool in Tools/webchecker/websucker.py.

CR Post to Ping.fm not working – resolved.

Last couple of months I was having a tough time getting the plugins in my wordpress to work with the ping.fm service.  This is the only service that I rely on to post my blogs. So, basically I was left with no mechanism to publish my new posts 🙁

Now thanks to this post I am able to use the plugin again and thus update my status at multiple places again.

some bash exercise for you

Here is some teaser for you, can you figure out how this works:

  <td>
    <div class="text codecolorer">
      echo ls<br /> <br /> !!:1-$

  </td>
</tr>

find duplicate entry in a list in bash with sed

Here I will take an example of rss2email list, but I guess I will be able to pass on the concept.

Here is example of the output of the r2e list command:

1: http://blog.amit-agarwal.co.in/feed (default: amitag@localhost)
2: http://feeds2.feedburner.com/AllAboutLinux (default: amitag@localhost)
3: http://feeds2.feedburner.com/Command-line-fu (default: amitag@localhost)
4: http://blogs.members.freewebs.com/Members/Blogs/viewBlogRSS.jsp?userid=29731143 (default: amitag@localhost)

Target here is to get the list of all duplicate entries if any. So, first we need to remove the numbers from the begining and the email ID from the end.

Short Information about loaded kernel modules

There are couple of ways you can find the information on the <a class="zem_slink" title="Loadable kernel module" rel="wikipedia" href="http://en.wikipedia.org/wiki/Loadable_kernel_module">loadable kernel modules. All these would always involve calling <a class="zem_slink" title="Lsmod" rel="wikipedia" href="http://en.wikipedia.org/wiki/Lsmod">lsmod to get the loaded kernel modules and then calling modinfo to get the info on the loaded modules. I will show you with examples:

$ lsmod
Module                  Size  Used by
cdc_acm                19616  0
vfat                    8744  9
fat                    41836  1 vfat

Simple rss to email service for your feeds on Linux with your/ISP server.

I like couple of blogs and feeds but the problem is that I keep forgetting to run the rss reader and would rather like to have the rss article&#8217;s emailed to me at regular intervals so that I can read them when I want to without having to make sure that I am at my desktop at home computer or remembering to start the rss client. That sounds simple and do-able so lets try to do that.
