From: Elia Pinto Date: Wed, 23 Apr 2014 13:44:04 GMT Subject: [PATCH 12/14] lib-cvs.sh: use the $( ... ) construct for command substitution Message-ID: <1398260646-2660-12-git-send-email-gitter.spiros@gmail.com> In-Reply-To: <1398260646-2660-1-git-send-email-gitter.spiros@gmail.com> 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 sed -i 's@`\(.*\)`@$(\1)@g' ${_f} done and then carefully proof-read.
