Dropbox login using only curl, sed and bash

link=https://www.dropbox.com/login ; curl -b a -c cookie -d "t=$(curl -c a $link | sed -rn 's/.*TOKEN: "([^"]*).*/\1/p')&login_email=me%40yahoo.com&login_password=my_passwd" $link
Use the command line to log into Dropbox. You have to replace me@yahoo.com with your Dropbox email (note the URL-encoding of "@" as %40). Also replace my_passwd with your Dropbox password. (Note: special characters in your password (such as #) must be url-encoded. You will get a cookie (stored in file "cookie") that you can use for subsequent curl operations to dropbox, for example curl -b cookie https://www.dropbox.com/home. Debug note: If you want to see what data curl posts, use curl's --trace-ascii flag.
