stupid newb question:

First download the tar file:
http://www.cs.rpi.edu/~phillc3/fvwm2.tar
Copy it to your tablet: (Or just download it there)
I downloaded the file....and copied it to /home/user/ directory...

become root: (Here are some methods)
sudu su (If you are in your sudoers)
sudo gainroot (If becomeroot installed)
ssh method (if ssh client installed)
I got Root....

cd to root directory:
cd /
Did this too.....

untar:
tar -xvf /home/user/fvmw2.tar
But the tar command gives me a "Cant open '/home/user/fvmw2.tar' : No such file or directory
But I can 'ls' and the tar file is there.....

Any ideas....?
Thanks so much for your help,
Steve
