I'm currently writing a bash testing framework, which requires to be as portable as possible.
So, at one point, I had to print a leading newline followed by some text which contains several expanded variables. This is the solution I've used.
echo -e "\n$number_of_specs ${units}, $number_of_specs_failed failed"
This seems okay but I'm not sure how portable that is compared to printing out the line using e.g. printf?
Any ideas or hints where I could find some references?
