I just downloaded
wolframscript on Linux. Downloading the "free wolfram engine for developers" gives me a
WolframEngine_12.0.0_LINUX.sh. I tried executing it but nothing happened.
How does one use this with

It needs to be executed under root user, and it is a shell script, so run
sudo bash WolframEngine_12.0.0_LINUX.sh
then wait for it to do its thing (the installation is interactive, it needs to be monitored).
This is what the http://support.wolfram.com/kb/46072 says, actually.
