Likewise, when an empty file is expected, use "compare /dev/null out", not "compare out /dev/null". I.e., specify the expected/desired contents via the first file name. Prompted by a suggestion from Bruno Haible in http://thread.gmane.org/gmane.comp.gnu.grep.bugs/4020/focus=29154 Run these commands: git grep -l -E 'compare [^ ]+ exp' \ |xargs perl -pi -e 's/\b(compare) (\S+) (exp\S*)/$1 $3 $2/' git grep -l -E 'compare [^ ]+ /dev/null' \ |xargs perl -pi -e 's,\b(compare) (\S+) (/dev/null),$1 $3 $2,' But manually convert this one: -compare out exp-$(echo $opt|tr ' ' _) +compare exp-$(echo $opt|tr ' ' _) out and avoid an inappropriate change to cfg.mk.
