Subject: git-rebase--merge.sh: use the $( ... ) construct for command substitution
X-Git-Tag: v2.1.0-rc0~184^2~35
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=f257482c9ccbb27e70f190da6a8152469b0fed1b;p=git-core%2Fgit.git

git-rebase--merge.sh: use the $( ... ) construct for command substitution

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.
