OSX/Linux/UNIX : Launch Another Copy of Dropbox

#!/bin/sh
# DESCRIPTION: RUN DROPBOX FOR MULTIPLE ACCOUNTS ON ONE COMPUTER
# By default, when you launch DropBox, it only lets you run one copy
# of the application. This script shows how I launch a second copy
# of Dropbox that uses a different account. This allows me to run
# one copy of Dropbox for my capspire account and one for my personal
# account. I won't explain how to save this as a shell script here,
# but if you need help, let me know. (Ossie)
#
# Obviously, adapt for your needs.

# Make a dropbox folder for the alternate account if not already done.
mkdir ~/Documents/Dropbox-capspire

# Change to that directory and reassign your HOME variable
cd ~/Documents/Dropbox-capspire
HOME=$HOME/Documents/Dropbox-capspire

# Launch dropbox, sending it to the background and swallowing output
# (Obviously, the script below assumes OSX, update for your OS)
nohup /Applications/Dropbox.app/Contents/MacOS/Dropbox &
