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.
The patch was generated by the simple script
for _f in $(find . -name "*.sh")
do
sed -i 's@`\(.*\)`@$(\1)@g' ${_f}
done
