Hi,

It seems that $( is a more recent form as it is mentioned in the
manual "When the old-style backquote form of substitution is used
...". Since these two forms, to a certain extend, are the same and $(
is introduced later, is $( preferred?

$() is more readable and it's much easier for nesting. For example, think how you can rewrite following statement with backquotes:

  var=$(echo $(echo $(echo $(echo foo))))
