The newest Magento Security Patch SUPEE-5994 has .sh extension and can be applied within command sh PATCH_SUPEE-5994_CE_188.8.131.52_v1-2015-05-15-04-34-46.sh
But if you don’t have ssh access to your Magento website you can use our github version of files which already patched for Magento version 184.108.40.206.-220.127.116.11. You can view & download patched files at this link.
This is definitely a life saver, especially for users not able to apply the patch the Magento way!
