How to move an org-mode file together with all attachments?

Question

I have a couple files, e.g. file-1.org, file-2.org in the same directory sharing the data/ directory for attachments.

I'd like to move file-1.org to a different location, create a new data/ directory in that location and move all attachments that belong to file-1.org to the new directory. Is there an automatic way to do this?

Answer 1

This command could do what you want:

find -E data -type f -iregex ".*($(cat file-1.org | grep -i ':id:' | perl -pe 's/^\s*:id:\s*(\w{2})([\w-]+)$/$1\\\/$2/i' | paste -s -d'|' -)).*" -exec rsync -R '{}' ~/temp/my-new-directory \;

Replace file-1.org with the org file whose attachments you want to move, and ~/temp/my-new-directory with the location of your new directory. A data directory will be created with the attachment files in them (if you want to move instead of copy, pass --remove-source-files to the rsync command).

This was tested on macOS. You might have to omit the -E flag on other platforms.

NOTE: Please do this on a copy of your files. I'm not an expert in emacs, have never used org-mode attachments and I'm not experienced with using this kind of hacky file manipulation. This could blow your org-mode folder into oblivion so back it up first.

Based on Marcel Samyn's answer, the following script worked for me under ArchLinux:

find data -regextype awk -type f -iregex ".*($(cat file-1.org | grep -i '^:id:' | perl -pe 's/^\s*:id:\s*(\w{2})([\w-]+)$/$1\/$2/i' | paste -s -d'|' -)).*"  -exec rsync -R '{}' ~/temp/my-new-directory \;

Use the following reduced script to get a list of files to be copied:

find data -regextype awk -type f -iregex ".*($(cat file-1.org | grep -i '^:id:' | perl -pe 's/^\s*:id:\s*(\w{2})([\w-]+)$/$1\/$2/i' | paste -s -d'|' -)).*"

Without the ^ in the grep command, I got false positives from email links containing ":id:".
