side-effect implementing the mv command

[Derick Centeno]

Recently I executed the following:

$ sudo mv ./libjavaplugin_oji.so /usr/lib/mozilla/plugins

Explanation:  I was within the directory where the java plugin existed
which is: /opt/ibm/java-ppc-60/jre/plugin/ppc/ns7.  The above was
executed from within the ns7 directory.  The intention was to move *.so
into the plugins directory.

The above may have created an unintended side effect; I
noticed that mv did not erase the original location of *.so but
created in fact a link from the within the plugins directory to *.so
within the ns7 directory! I don't have a theory why this happened other
than to guess that as I did not provide a new filename for 
the mv command to rename the *.so file mv proceeded to create a link to
the original *.so file.

Ideas?

Thanks.
