A simple way to identify the locations of null characters in a flat file is by using the following command. Works well each time for me. :)

 

tr ‘\0′ ‘@’ < INPUT_FILE > OUTPUT_FILE

 

I LOVE UNIX!

Just a while ago while I was making some changes to the config and all of a sudden I could not access the software. Unexpected Error “object reference not set to an instance of an object” shows up and I can’t seem to access the software anymore.

PuttyCM - Unexpected Error

PuttyCM - Unexpected Error

Then I remembered the last I changed was the “Show Tray icon” option to disabled.

I re-enabled the option and…

Bingo.. I can access the program again.

Hope this will help you too. :)

While searching big brother G, I found the solution here:- how to extract a range of lines from a file provided by zazzybob.

Here’s the solutions:-

You could also pipe though sed to extract the range – e.g.
blah | sed -n ’1,1000p’ | blah
to extract the first 1000 lines of the file

How I uses it:-

cat file.unl | sed -n ’1,100p’ > out100.unl

Cheers.

Well I still think it is cool but at times, I’d want peace of mind and don’t want to get updated on what is going on with the people around me.

Here is how I could turn off Google Buzz.

Once you have logged into Gmail, scroll down to bottom of the page. You’ll see the “Turn off Buzz” link. Just click on that and you are then Buzzed off.. :D

Turn off Google Buzz
