X-Git-Tag: v2.0.0-rc1~8^2~2
X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/b352891021d74528f668306d0882633cc0673a89

git-tag.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.
