# This script supports Linux distributions (alpine, arch, centos, debian, fedora, rhel, ubuntu) and macOS.
# For it to work properly you will need either jq and openssl packages installed on your system or sudo privileges for the script.
#
# You need a couple of environment variables to set up and you can call this script from terminal:
# ARTIFACT_PATH=LOCAL_PATH_OF_THE_ARTIFACT_TO_BE_UPLOADED \
# AUTHORIZATION_TOKEN=BITRISE_RM_API_ACCESS_TOKEN \
# CONNECTED_APP_ID=APP_ID_OF_THE_CONNECTED_APP_THE_ARTIFACT_WILL_BE_UPLOADED_TO \

I only found this, because I ran this script in an alpine docker image and it told me, that the stat properties are wrong. So I think, currently this script does not work with Linux distros.

You were right. I have fixed a couple of problems for Linux distros, but I suggest to use the more "official" script maintained within our company for this: Upload script. This has only been created recently.

However, you might have problems within a docker image as 'sudo' is not always available there to install commands (if you already have jq and openssl installed within the container it won't matter tho.

I will delete this gist in a couple of weeks to not have to maintain this in two places.
