The Git CodingGuidelines prefer the $(...) construct for command substitution instead of using the backquotes `...`.
The backquoted form is the traditional 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.
The patch was generated by:
for _f in $(find . -name "*.sh")
do
perl -i -pe 'BEGIN{undef $/;} s/`(.+?)`/\$(\1)/smg' "${_f}"
doneand then carefully proof-read.
