Woohoo -- thank you Joey!
Here is my complete example which seems to work quite neatly. One aspect which you might (or not -- shouldn't matter to me but bash people might appreciate): could \"${filename}\" (if provided to examinekey) be passed into `format` as well? that would allow for easy looping like in this example, but on more than one key at a time.
Unrelated, just curious -- what is the best way to \"chain\" multiple batch processes in bash, like here `examinekey` and `registerurl`?
```bash
$> cat ./addurl-uberfast.sh
#!/bin/bash
export PS4='> '
set -x
set -eu
cd \"$(mktemp -d ${TMPDIR:-/tmp}/dl-XXXXXXX)\"
md5=f92bbc617f8c8714a251f1f208af37a0
size=6605
filename=GLwDrawA.h
url=http://www.onerussian.com/tmp/$filename
git init
git annex init
echo MD5-s$size--$md5 $filename | \
git-annex examinekey --batch --format='${key} ${objectpath}\n' --migrate-to-backend=MD5E | \
while read key objectpath; do
git-annex registerurl \"$key\" \"$url\"
# examinekey does not know ${filename} in its format so such looping isn't exactly
# possible easily in bash ATM
ln -s \"$objectpath\" \"$filename\"
git add \"$filename\"
git annex get \"$filename\"
git annex drop \"$filename\"
done
```
