For all the linux salesforce.com users, here’s how you can use data loader on a linux.

First download the hacked version of the data loader that was made by Bluewolf’s own, David Lin

Then follow these directions:

1. Extract the files to a location of your choice (an ApexDataLoader_12 subdirectory already exists) ie. tar xvzf ApexDataLoader12.tar.gz
2. In the root of the extracted directory make executable the script that I wrote to call run the jar with the necessary java parameters
   ie. chmod a+x dataloader
3. Set your JAVA_HOME variable
4. Run the script(from the directory) and migrate data ie. ./dataloader

Enjoy!
