Shell Programming and Scripting

Perhaps, it would be best if you follow up with some more information in your other thread you started: https://www.unix.com/302946817-post1.html

Usually, when people do not respond to your post is because it is not clear or is missing the necessary information to give you a solution.
I suggest you go back to that thread and add an example of how your file directory tree looks like. Post the output of ls -l from the directory you want to perform the extraction. Also, it might help what kind of errors or warnings you get when command is executed.
Finally, it is most helpful if you explain what do you think or expect to happen and it is not occurring.

Your stated goal was to copy files with filename extensions from one directory into a subdirectory named by the file's name with the filename extension removed. I don't see any connection between that goal and running any of the commands:

Code:

rm -f $dir/*.tar
mv -f $dir*tgz* $dir/
gunzip $dir/*.tgz
      or
tar xvf /tar/*.tar

So, I am still lost...

you cant tar in script unless you will do this

tar xvf tareball -C "Directory you want to extract"
