From: Elia Pinto Date: Tue, 25 Mar 2014 17:23:00 GMT Subject: [PATCH v2 039/142] t4006-diff-mode.sh: use the $( ... ) construct for command substitution Message-ID: <1395768283-31135-40-git-send-email-gitter.spiros@gmail.com> In-Reply-To: <1395768283-31135-1-git-send-email-gitter.spiros@gmail.com> 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 Signed-off-by: Elia Pinto --- t/t4006-diff-mode.sh | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/t/t4006-diff-mode.sh b/t/t4006-diff-mode.sh index 0591149..76f643b 100755 --- a/t/t4006-diff-mode.sh +++ b/t/t4006-diff-mode.sh @@ -13,7 +13,7 @@ sed_script='s/\(:100644 100755\) \('"$_x40"'\) \2 /\1 X X /' test_expect_success 'setup' ' echo frotz >rezrov && git update-index --add rezrov && - tree=`git write-tree` && + tree=$(git write-tree) && echo $tree ' -- 1.7.10.4
