Actually POSIX (more specifically KSH which essentially became 
the POSIX shell) introduced the $(...) to replace the `...`.  Many 
books on the shells talk about the backquote or grae accent as being 
deprecated, but the documentation for KSH specifically calls the 
backquote form "obsolete", but does not deprecate it.  So, let me back 
of from my use of deprecated, because both SH, BASH, and KSH the 
backquote or grave accent is retained for backward compatibility.
