Bash Script: Install Drupal/Wordpress Packages with getopts

I run a Drupal and a WordPress site off of a single remote server hosted by Site5. To simplify the process of decompressing and installing modules (Drupal), plugins (WordPress) and themes (both), I wrote a simple bash script using the getopts utility to allow me to decompress and send packages in one line. I am excited about this utility because it marks the first time I've successfully used getopts.

#!/bin/bash

# Automatically decompress and upload the specified plugin(s) to a
# server specified by its namesack variable. Different operations are
# performed based on whether the module is for drupal (-d) or WordPress
# (-w). The plugin can be an actual plugin (-p) or a theme(-t). This
# is significant because it is my first shell script to inculde
# command-line parameters. The decompresses the files to the tempdir
# variable (/tmp), and then uses scp to send them to the server.
# Presently runs from the same directory as the package.

shift $(($OPTIND -1))

then
        servepath=public_html/front/sites/all;

        $DEBUG tar -xzf ${modname}*.tar.gz;

        then
                endpath=/modules;
        else
                endpath=/themes;
        fi

elif [ "$wflag" ]

        servepath=public_html/napword/wp-content;

        else

        fi

# Or the user enter something weird
else
        printf "missing options\n"
        printf "Usage: %s [-d] [-w] [-t module] [-p module]
        " $(basename $0)
        exit 2
fi

$DEBUG scp -r ${modname} ${server}:${servepath}${endpath};
$DEBUG rm -rf ${modname};

The $DEBUG variable is a trick I learned from someone at Purdue's Rosen Center for Advanced Computing. If you call the script in the usual manner, bash will ignore $DEBUG. To see what the script would do if it were being run, preface the call with DEBUG=echo.
