From: Elia Pinto Date: Tue, 25 Mar 2014 17:22:26 GMT Subject: [PATCH v2 005/142] git-rebase.sh: use the $( ... ) construct for command substitution Message-ID: <1395768283-31135-6-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' ${_f} done Signed-off-by: Elia Pinto --- git-rebase.sh | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/git-rebase.sh b/git-rebase.sh index 5f6732b..a209ab9 100755 --- a/git-rebase.sh +++ b/git-rebase.sh @@ -462,8 +462,8 @@ then else if test -z "$onto" then - empty_tree=`git hash-object -t tree /dev/null` - onto=`git commit-tree $empty_tree
