Backup of files in the directory.

I was working on some scripts and the changes that I was making in the scripts was very dynamic, which I did want to keep backing up in the version control system. But for the peace of my mind, I wanted to keep a copy of the scripts, whenever it was in working state.

Since I had multiple files, so it would make more sense to have a script that could copy all the files in the current directory to “old” directory without over-writing the existing files. So, I wrote a script that would postfix the files with a number. With this approach, finally what I had was the following:

Compare files excluding certain lines.

Quick tip, you can use any expression for the sed commands in the (). With this trick you can redirect the stdout of 2 commands to the diff command. This might become very useful, if you want to compare 2 files, excluding the first  line.

diff <(sed '1d' file) <(sed '1d' file2)

More interesting example is where the string ABC is converted to abc before comparing in the second file with the following command:

Cont: Get yourself some more conkyrc files.

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

Script to get yourself some conkyrc files

Continuing from where we left, here is a script that can do all this for you 🙂

curl http://ubuntuforums.org/showthread.php?t=281865\&page=$i | sed -n '/\\/pr/ p'| sed '// 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

This will create couple of conkyrc.files in the current directory. Each of these is one from the web-page that I mentioned earlier. So, enjoy….

Get yourself some conkyrc files.

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 🙂

some interesting alias

For this time, I will just give you a link to to bashrc file.

Installing Full Blin g theme on N900

I was going through the post : http://talk.maemo.org/showthread.php?t=46739
and found the theme quite intruging but not complete to the point where I can download the deb file and install it in /usr/share/theme/ dir with simple commands “apt-get” or at max just use mkdir command to create the dir and dump everything in that dir. So, I wrote this couple of bash one liners to copy the required files to my N900.
