The Git CodingGuidelines prefer the $( ... ) construct for command substitution instead of using the back-quotes, or grave accents (`..`).
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 backslash character. Because of this the POSIX shell adopted the $(…) feature from the Korn shell.
