Hi Hermann here, I'm the upstream maintainer.
Thanks for you interest in our work. Let's have a look at the part were you complain about. set +e RN=$(rename -V 2>/dev/null| grep File::Rename) if [ ! -z "$RN" ] ; then use_to_rename='rename' fi if [ -z "$RN" ] ; then RN=$(prename -V 2>/dev/null| grep File::Rename) use_to_rename='prename' fi if [ -z "$RN" ] ; then RN=$(perl-rename -V 2>/dev/null| grep File::Rename) use_to_rename='perl-rename' fi if [ -z "$RN" ] ; then RNUL=$(rename -V 2>/dev/null| grep util-linux) if [ -z "$RNUL" ] ; then RNUL=$(rename.ul -V 2>/dev/null| grep util-linux) use_to_rename='rename.ul' else use_to_rename='rename' fi fi set -e So, what does that mean? We look for which rename tool is available and use the one we find first. That may differ from distribution to distribution. But looking for it, couldn't be a bug, or could it? Anyway, this is a developer tool which will never be part of any debian package. It's part of the source for documentation of what we do, and how we do it. Please consider to mark this report as done. regards hermann
