Do you get any errors?
What does the command

Hello, No I am did not get any error while running the un-tar command....Moreover in the screen it showing that its doing the un-tar, but the when commands execution finish it shows the the same

folder_test
      New.tar

Please help

You did not post what the file command shows.
When you are at it you could add the output of

tar -tvf New.tar

Hello zaxxon,

I tried the above command

$file New.tar

ouput is:
New.tar: tar archive

after using the coomand

tar -tvf New.tar

result:
its executing successfully but it not doing the un-tar

Ok.
-t is for listing the archives contents, that's ok too. I wanted to see the contents. Do you mind listing them? Thanks.
