For example:

l8get LC81690352014169LGN00

The echo at the end is to remind myself of the syntax for extracting bands 8, 4, 3, and 2. (Pansharp, Red, Green, Blue)

On OSX this would go into your ~/.bash_profile file.

Requires gsutil from https://developers.google.com/storage/docs/gsutil_install

Most useful in conjunction with USGS' Earth Explorer: http://earthexplorer.usgs.gov/

function l8get() { id="$1" path=${id:3:3} row=${id:6:3} yr=${id:9:4}

gsutil cp gs://earthengine-public/landsat/L8/$path/$row/$id.tar.bz .

echo ""
echo "tar -jxvf *.tar.bz '*_B[4328].TIF'"

}
