Cont: Get yourself some more conkyrc files.

2011-10-12 1 min read Bash Learning Linux

Last time we got ourselves some conkyrc files from the ubuntu forums. But that scripts gets the files only from the First page of the thread. Lets extend this further and get the script to get all the conkyrc files.

There are some 1048 pages in the thread, I am showing pages 1 to 3 but you can change 3 to whatever number you want 🙂

count=0
for i in {1..3}
do
    >.test
    >conkyrc
	echo "Getting page $i"
	curl http://ubuntuforums.org/showthread.php?t=281865\&page=$i |\\
         sed -n '// d'|\
         sed 's##\n-----------------------------------\n\n\n#' \
         >conkyrc
	dos2unix conkyrc
	cp conkyrc .test
	while [ $(wc -l .test|sed 's/[^0-9]//g') != 0 ]
	do
		sed -n '1,/------------------------/ p' .test|sed '$d' >conkyrc.$count
		diff .test conkyrc.$count |sed 's/^<.//'|sed '1, /---------------------/ d;2d'>.test
		((count++))
	done
	echo "Files so far are : $count"
done

If you are looking for some nice conkyrc files, then you can head over to :

Ubuntu Forums

In this thread you can see some very nice conkyrc files with screenshots. You can browse through the thread and get the one that you like. But if you are like me and would like to download all of them to see the features and commands in each of them then you would need to copy each of these files and paste them separately. But if you have to do everything manually then there’s not much of being on Linux 🙂

[ad#ad-2]

I am testing some of my scripts to work on a very old system and there the versions of the most popular applications are very old, real old :(. So, some of things that I am very used to since last couple of years, do not seem to work as expected and I need to keep verifying a lot of things on the server, very inconvinient to keep testing the script on the server (need to connect on VPN) just to test some very simple things.

Something that I have been searching for a long time, finally some look inside the <a class=“zem_slink” title=“Procfs” rel=“wikipedia” href=“http://en.wikipedia.org/wiki/Procfs" _mce_href=“http://en.wikipedia.org/wiki/Procfs">/proc got me what I wanted. Hope this will save someone’s day. So far, the only option I could think of was to run conky which becomes a little heave on some of the very old laptops I have to use sometimes 🙁

Solaris dump analysis

2011-05-18 1 min read Solaris

I had to debug a solaris crash dump and had no ides. Google search wasn’t much useful until finally I found this article:

http://cuddletech.com/blog/?p+AD0-448

have a look at this article, this suggests how to debug the core and find the offending process and root cause of the core in case of kernel panic.
