Subject: unimplemented.sh: use the $( ... ) construct for command substitution
X-Git-Tag: v2.8.0-rc0~103^2~82
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=92bea9530ba2a69cc0f0e3a3d67e60fafb2444d9;p=git-core%2Fgit.git

unimplemented.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
	perl -i -pe 'BEGIN{undef $/;} s/`(.+?)`/\$(\1)/smg'  "${_f}"
done

and then carefully proof-read.
