CLI Color and bash prompt.. some colored fun with prompts in bash

2010-06-29 5 min read Bash Fedora Linux

There are two ways to do it, one is with tput command. We will see that some other time, today we will consider the escape sequence way.

First we need to understand the colors as understood by bash. Some time back a fried of mine gave me this little script to find the colors. You can download it <a href="http://blog.amit-agarwal.co.in/2009/03/bash_colors" target="_blank">Script bash colors. Here is the script

blogtk — Unsupported XML-RPC protocol

2010-06-29 2 min read Linux

Earlier I had talked about this blog client, did I. If not then there is a nice blogging clinet called BloGTK, which can be used directly to post into the blog.

So today I reinstalled it and I was completely at loss with the client being unable to start with the error below:

/usr/lib/python2.5/site-packages/blogtk/BloGTK.py:407: GtkDeprecationWarning: gtk.TRUE is deprecated, use True instead

Getting your wordpress self hosted stats on your console with bash script.

2010-06-29 3 min read Bash Learning

Some time back I wrote a blog on how to get your site stats using curl in <a class="zem_slink freebase/en/bash" title="Bash" rel="homepage" href="http://tiswww.case.edu/php/chet/bash/bashtop.html">bash shell. Today we will use the same script to get the stats every few seconds on the terminal on the same line, similar to progress meter.

Here is the script and the description:

wordpress blog stats monitoring from remote using curl and bash and send it in mail.

2010-06-25 3 min read Bash Fedora Linux

Here’s something that I had been planning to do for sometime now. I have my blog on wordpress and have Statpress plugin installed. The plugin does give me a good idea of the visits to my site. Now, I have to keep logging in every now and then to check the stats. Also since I did not want to spend some more amount 🙂 so I do not have the shell access to the server, too bad 🙁
