I've heard this a couple times now, but never had anyone explain why the $( ) format is preferred over the back quote in bash scripts. I have begun to try remembering to use the $( ) format in my scripts now, but I still find myself using back quotes quite often. So why is back quotes not considered a good method of shelling out a command to the system?
