I couldn't spot any way to make something like `ls -j` (j is an illegal option) throw an exception in ruby (as opposed to simply outputting the system error message). The closest I could find is what you suggest (checking $?), or using something like this [1], which would require changing syntax: system('ls -j', exception: true) Would be great to know if there's some easy callback or, ideally, a global setting one can make so a ruby exception is thrown if there's an error running system commands using the backtick syntax.
