Small tweak...   Use && instead of semicolon.

If you do:

     cd /whatever ; somecmd

Then somecmd will be run EVEN IF the cd failed.  So you might end up 
doing something in the wrong directory.  Even best case scenario, it'll 
be hard to troubleshoot what failed, since somecmd will still run, it'll 
just fail because it's in the wrong directory.

So it's better to do this:

cd /whatever && somecmd

In this case, the somecmd command is only executed if the CD command was 
successful.  Therefore, if the directory change doesn't work, the error 
message will be the one from the cd command, and the somecmd command 
won't be executed.
