The script is run in a subshell and can not affect your running shell's
working directory (unless you invoke it by ". script-filename", in which case
you are running its commands in the context of your running shell).

Observe:

    $ cat foo.sh
    #!/bin/sh
    cd /tmp

Just trying to execute the script:

    $ ./foo.sh
    $ pwd
    /home/kayvan

But, using "." to execute the commands in the current shell:

    $ . ./foo.sh
    $ pwd
    /tmp

Another solution if you want this to affect your shell is to use the "alias"
command or shell functions.

Read "man bash" and http://www.tldp.net/HOWTO/Bash-Prog-Intro-HOWTO.html
