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?
