git-annex very appealing, but have been moving files without it for a while, here is a little script that may help you through the transition. I've just converted my MP3 library to git-annex, but, now I must convert all my copies of the library on various computers to track one (or more) of them. The trick is to teach git-annex about the already existing files, as re-downloading a 20GB library through a 80 KB/s upload DSL line doesn't sound that funny. Here is how I did it.First, convert one repository to using git-annex. Then, switch to another computer, move away the directory containing the files to a backup directory, and git clone the first repository. Then, from the directory created, run:
~ ./import path/to/old/backup/copy
Where import is the following script:
#! /bin/bash
src="$1"
IFS=$'\n'
for f in $(find -type l); do
if stat -L "$f" >/dev/null 2>/dev/null; then
echo "File $f ok"
else
tg=$(readlink "$f" | sed 's/.*git/.git/' )
dir=$(dirname "$tg")
if [ -r "$src/$f" ]; then
mkdir -p "$dir"
cp -avl "$src/$f" "$tg"
fi
fi
done
Once this is done, you'll need to run
~ git annex fsck
Of course, there is no warranty !! It saved me lots of download time, but it could irretrievably damage your data, put your dog in danger or set fire to your house, so use with care !
