Argh!  Here's a fix to a bad bug in the last version (cp "$1.image"
"$1.changes" "$d" => cp "$1.image" "$1.changes" "$2")!!
-------8<-------
#!/bin/sh
# copy image and changes
force=0
if [ "$1" = -f ]; then
force=1
shift
fi
if [ $# != 2 -o "$1" = "-?" -o "$1" = --help ]; then
echo "usage: $0 [-f] image-name-no-ext [image-name-no-ext|dir]"
test $# != 2 && exit 1
exit 0
fi
if [ -f "$2.image" -o -f "$2.changes" ]; then
if [ "$force" = 0 ]; then
echo "$2.image and/or $2.changes already exist." 1>&2
exit 1
fi
elif [ -d "$2" ]; then
if [ -f "$2/`basename "$1"`.image" -o -f "$2/`basename "$1"`.changes" ];
then
if [ "$force" = 0 ]; then
echo "$2/`basename "$1"`.image and/or $2/`basename "$1"`.changes already
exist." 1>&2
exit 1
fi
fi
cp "$1.image" "$1.changes" "$2"
exit 0
fi
cp "$1.image" "$2.image"
cp "$1.changes" "$2.changes"
