Extracting .tar file isn't working
===

Thanks ahead of time for all your help guys! As a beginner user I really appreciate the help!

**My Machine/OS:**
Mac OSX 10.5.8, 32-bit

**What I'm trying to do:**
Extract and install Apache Maven, from the website http://maven.apache.org/download.html . 

**What I've done:**
Downloaded the binary *.tar.gz* file from the website, and using the shell, moved the downloaded file to the appropariate directory, and extracted the *.tar* out of the *.tar.gz* by using `gunzip -v filename.tar.gz`, resulting a *.tar* file. Now I'm trying to extract the *.tar* file using `tar -xv filename.tar`. 

**My Problem**
The extraction doesn't seem to be working! After I've typed the `tar -xv filename.tar` command and hit enter, the shell isn't returning any output, and doesn't seem to complete the extraction. It stays indefinitely with the empty line returned after hitting enter.


**My Attempts**
Examining the directory from another Shell window, both while `tar` is running and after quitting the shell while the process is running, doesn't show any changes in the files contained; i.e. the only file/directory present is the original *.tar.gz* file. I've also tried deleting the file along with the directory containing it, re-creating the directory, re-copying the file into the directory, and then re-trying the `tar -xv filename.tar` command. The result is the same


Thank you so much everyone!
