vim search multiple files

Searching some pattern in multiple files is something that is required very often. There are multiple ways to do it, like <a class="zem_slink freebase/en/grep" title="Grep" rel="wikipedia" href="http://en.wikipedia.org/wiki/Grep">grep, <a class="zem_slink freebase/guid/9202a8c04000641f8000000006b66ec6" title="Ack (command-line utility)" rel="wikipedia" href="http://en.wikipedia.org/wiki/Ack_%28command-line_utility%29">ack, find and so on so forth. But if your editor already has the capability to do that, then why leave your favourite vi and go to shell. I will point you to some scripts and some wiki pages on how to do this 🙂

Running Nested X server

Today I was trying to do a XDMCP connection to the other server ( which is solaris, not sure if that matters) so I used the Xnest server. and used the following command:

Xnest :1 -ac -query

And I was getting the error:

AUDIT: Tue Dec 2 20:40:03 2008: 1470 Xnest: client 2 rejected from IP <>

I tried allowing the host to use the display but not use. The command I used was

Photo Compositing with the GIMP

Basing from my previous <a class="zem_slink freebase/en/gimp" title="GIMP" rel="homepage" href="http://www.gimp.org/">GIMP article titled Creating Pseudo-3D Imagery with GIMP, you learned how to do some basic selection manipulation, gradient application, faking <a class="zem_slink freebase/en/depth_of_field" title="Depth of field" rel="wikipedia" href="http://en.wikipedia.org/wiki/Depth_of_field">Depth of Field, etc. In line with that, I’m following it with a new article very much related to the concepts discussed therein but we’ll raise the bar a bit by having a glimpse on <a class="zem_slink freebase/en/compositing" title="Compositing" rel="wikipedia" href="http://en.wikipedia.org/wiki/Compositing">compositing, where we’ll use an existing <a class="zem_slink freebase/en/image" title="Image" rel="wikipedia" href="http://en.wikipedia.org/wiki/Image">image or <a class="zem_slink freebase/en/photograph" title="Photograph" rel="wikipedia" href="http://en.wikipedia.org/wiki/Photograph">photograph and later add in our <a class="zem_slink freebase/en/dimension" title="Dimension" rel="wikipedia" href="http://en.wikipedia.org/wiki/Dimension">2-dimensional element seamlessly with the said picture.

Recursive Regular Expressions

<img src="http://blog.amit-agarwal.co.in/wp-content/uploads/2010/08/yo-dawg-regex.jpg" alt="Yo dawg, I heard you liked regular expressions, so I put a regex in your regex so you can match while you match!" align="bottom" /> The <a class="zem_slink freebase/en/regular_expression" title="Regular expression" rel="wikipedia" href="http://en.wikipedia.org/wiki/Regular_expression">regular expressions we use in our daily lives are actually not that “regular.” Most of the languages support some kind of extended regular expressions that are computationally more powerful than the “<a href="http://en.wikipedia.org/wiki/Regular_expression">regular” regular expressions as defined by the <a href="http://en.wikipedia.org/wiki/Formal_language">formal language theory.

bash – change theme for gtk in gnome and take screenshot from script.

I wrote a blog on bash script to change the icon/cursor theme using a bash script. Lets extend the same concept a little more and use the script to change the gtk theme for gnome and at the same time take a screenshot also.

#!/bin/bash
path=&#8221;/tmp/screenshot&#8221;
[[ &#8221;$1&#8221; == &#8221;&#8221; ]] && time=5 || time=$1
[[ &#8221;$2&#8221; == &#8221;&#8221; ]] && (
cd ~/.themes
cont=&#8221;y&#8221;
echo &#8221;Select one of the icon themes&#8221;
echo &#8221;When you like some theme just press Ctrl+c&#8221;
for i in *
do
[[ -d $i/cursors ]] || (
echo &#8221;Now trying …. : $i&#8221;
gconftool-2 –type string -s  /desktop/gnome/interface/gtk_theme &#8221;$i&#8221;
sleep 1
j=$(echo &#8221;$path/$i&#8221;).jpg
import -window root -quality 95 &#8221;$j&#8221;
sleep $time
)
done
) || gconftool-2 –type string -s  /desktop/gnome/interface/gtk_theme &#8221;$2&#8221;
