I'm not a guru, but I already posted answers to this.  I'll summarize
one last time.  If you want the current shell to execute a script, you
have to tell it to specifically.  If you simply invoke a script on the
command line, that script runs in a child process--same as any other
command.  To get the current shell to execute commands from a file (other
than the tty):

1.  Use the "." command to tell the shell to execute commands from the file
    given as its argument.

2.  Make the script into a shell function.

3.  Define a shell function that uses the "." command to interpolate the text
    of an existing script:

	ncd() {
	    . $HOME/bin/ncd
	}

4.  Or, if you can do the job with a one-liner, just do it:

	ncd() {
	    cd `find . -name "*${1}*" -type d -print` ; pwd
	}

Try it!
