It is the case. Every shell I've ever heard of does ``, the $() thing showed up with the Korn shell and got propagated into various other shells. I believe `` is more widely supported, and for a maximally portable shell script (which admittedly this does not need to be) is thus superior wherever it will do the job. If one of BB's own shells doesn't support $() then that right away tells you which style to prefer for this script. -- Jim _______________________________________________ busybox mailing list busybox@busybox.net http://busybox.net/cgi-bin/mailman/listinfo/busybox
