You can put '.' in your path. In 'csh' or 'tcsh' you do this as follows:

    % set path = (. <rest of your path>)

In 'sh' and 'bash' you do it like:

    $ PATH=.:<rest of your path>
    $ export $PATH

If a shell script contains 

     #!/usr/bin/sh    
     (or #!/usr/bin/csh)

as its first line, and the file is executable (ie. has the 'x' bit on), 
it will be run by that shell.

So, if you have '.' in your path and the script contains '#!/usr/bin/sh'
you can simply type 'install'.
