How do I supress the output of:
spago build
or npm run build

I only want to know if the build succeeded. I do not want to see all the noise.

I can try to figure out if things worked by other means.

#!/usr/bin/bash

rm /tmp/compile_purescript.txt
npm run build &>/tmp/compile_purescript.txt
cat /tmp/compile_purescript.txt | grep -P "Build succeeded|Error found"
