Use $(...) notation for subshells in system tests
The changes were mostly done with sed: find . -name '*.sh' | xargs sed -i 's/`\([^`]*\)`/$(\1)/g' There have been a few manual changes where the regex wasn't sufficient (e.g. backslashes inside the `...`) or wrong (`...` referring to docs or in comments).
