Finally I got it: Add this to your .bash_profile

I implemented the above as a Python script that makes wrapper scripts instead of aliases. You will need to put ~/bin/mankoffmagic in your path. If you want the wrappers to be updated automatically, run it regularly from cron or somesuch.

# This script automagically updates a set of wrapper shell scripts in
# ~/bin/mankoffmagic which call Mac apps installed in /Applications.
#
# Inspired by mankoff's shell alias posted on apple.stackexchange.com; see:
# http://apple.stackexchange.com/questions/4240/concisely-starting-mac-os-apps-from-the-command-line/4257#4257
#
# Notes/Bugs:
#
# 1. Does not follow symlinks (aliases?)
#
# 2. Assumes that application names do not contain double-quotes.
#
# 3. Not very smart about finding the actual binary (it guesses). This is
# wrong sometimes, e.g. Firefox. Probably a deeper understanding of the app
# package structure would fix this.

Finally I got it: Add this to your .bash_profile

function foomagick() {
    ls /Applications/ | grep "\.app" | grep -v iWork | while read APP; do
        # clean it up                                                           
        a=`echo $APP | sed s/\ //g`;
        a=`echo $a | sed s/\'//g`;
        echo alias ${a%.*}="'open -a \"${APP%.*}\"'"
    done
}
foomagick > foomagick.tmp
source foomagick.tmp
rm foomagick.tmp  

Now the following work:

Skim # open Skim.app
Skim foo.pdf
FireFox http://google.com
FireFox google.com # ERROR. Looks for local file.

Finally I got it: Add this to your .bash_profile

function foomagick() {
    rm -f ~/.foomagick.tmp
    ls /Applications/ | grep "\.app" | grep -v iWork | while read APP; do
        # clean it up                                                           
        a=`echo $APP | sed s/\ //g`;
        a=`echo $a | sed s/\'//g`;
        echo alias ${a%.*}="'open -a \"${APP%.*}\"'" >> ~/.foomagick.tmp
    done
    source ~/.foomagick.tmp
    rm ~/.foomagick.tmp  
}
foomagick()

Now the following work:

Skim # open Skim.app
Skim foo.pdf
FireFox http://google.com
FireFox google.com # ERROR. Looks for local file.
