I used ls -l mysoftware/on two different machines, each running ubuntu 12.04.But the 'total' returned by this command is different on the two machines. On one machine it is printing 6, and on another machine it is printing 24. Although I can see same number of files listed.   Actually I copied compressed folder mysoftware.tar.bz2 from my pendrive to these machines and then untar using the following command:sudo tar xvfj mysoftware.tar.bz2After that I used ls -l as above.Since I was not able to install some software on the machine where I'm getting 6, I suspect some files are missing. The question is can the two 'total' be different on different machines?        
Is it possible to have total no. of blocks taken by same files be different on two PCs?
ls;tar
