This is more a unix shell script question than anything but I'm curious; why the recent changes as denoted in the git update below and this subject line: use $() instead of backticks in talkwith I may not be super current on shell script behavior and trends byt why is $(command) better than `command`? I've alwys used the tic marks because I've seen that most often used. No better reason than that but I figured I can change my approach if this other deal is better or more appropriate. Curious minds would love to know. <smile>
