The backquoted form is the historical method for command substitution, and is supported by POSIX. However,all but the simplest uses become complicated quickly. In particular,embedded command substitutions and/or the use of double quotes require careful escaping with the backs= lash character. Because of this the POSIX shell adopted the $(=E2=80=A6) fea= ture from the Korn shell.
