qsub error - /bin/sh :no such file or directory

I was working with intel MTL Linux cluster recently and ran into this error. I had a shell script that would run another shell script which in turn runs my executable files. I created a script called batchjob to run my shell script.

Invariably, it kept throwing error at me. It said bin/sh no such file or directory. I took me a while to figure out what was wrong. In my first script I used something like
sh args1 args2
There is one issue with this. The file is under a folder called project and the batch server does not know the location. So the first change was to add the directory path. So it became:
sh $HOME/project/ args1 args2
Although, it did help the program still had errors. I was passing a data file as input to my program as args1. I had to do apply the same trick there too.
sh $HOME/project/ $HOME/project/data/exe.dat args2
The other change I made was to remove the line #!bin/sh, you don't have to do that if you are sure the script runs without qsub.

Another issue was to set the compiler variables. So I added the following command:
source /opt/intel/bin/ intel64
 After these changes the script runs just fine. Hope this will help someone.

Transfer iTunes Music between two computers or laptops

In a recent visit to Apple Store, I figured out how to move your iTunes music from one computer to another. If you want to transfer songs from your home computer to your work computer it is possible. Also, if you already bought songs you can transfer them to other computer without breaking the law. Follow these simple steps and you are good to go.
