In order to upload sketches into the Arduino 101 on a computer running Linux, I followed the instructions on the "Getting Started Page"
In order to upload sketches, it instructs you to do the following:
Linux only: some distributions need to be configured to perform the upload. After installing the core, execute sudo ~/.arduino15/packages/Intel/tools/sketchUploader/1.6.4+1.14/scripts/create_dfu_udev_rule inside a shell to gain upload permissions.
At least in my case, the folder location for the create_dfu_udev_rule was as follows:
sudo ~/.arduino15/packages/Intel/tools/arduino101load/1.6.4+1.18/scripts/create_dfu_udev_rule
Hope this is of help to anybody.
