I have had this problem for a very long time, had several discussions with friends, and tried searching relating info online. All efforts were in vain so I decide to give a shot here.

I have lots of files that I would like to annotate. Not necessarily are they pictures or documents, but also audio/video files. Now, I understand that there are ways to annotate a PDF, and there are ways to add metadata to PDF/mp3/mp4.., but those methods are not enough for me.

More specifically, when it comes to PDF files, usually I would like to take some notes in my favorite format. The current best way I can think of is to create another file with the same name and put them in the same directory (or tar them together), e.g. Learn-How-to-Learn.pdf Learn-How-to-Learn.pdf.note.md. However, I found this method cumbersome, for instance it is hard to always link them together and with their names synced.

When it comes to mp3/mp4 files, I also want to link them to other files that contain my notes. For example,

00:45:37,I would like to listen to this part again,20190610T19:03:56
01:03:55,Donald Knuth made a good point on blah blah,20190610T20:00:03

These examples go on and on.. I feel that this is very useful, and there must be some clever solutions out there. But to my surprise, I haven't found any! Please let me know if I should be clearer.. sincerely I would like to have a beautiful solution. Thank you in advance!

Based on your question, it would be something like https://github.com/ljmdullaart/a-notate. Yes, it is written (by me) after you asked this question, and it is inspired on your question.

  • It's thrilling to hear that you write a script for my question. I am still testing it, but perhaps a minor suggestion will be helpful: file2do=$(pwd)/$1. Other than that, I am still testing it (and having fun). Also, I really like the way you shell script. Would you mind sharing Andreas Kusalananda Khäri's lesson in cleaner shell programming? I cannot find it online.

  • Another feature (bug?) that I found confusing in the script is that around line 40, using grep -q blahblab seems not enough for me. The file overview will not be updated if the name of file is changed to a substring of the original one. For example, changing README.md to README.m is not a good idea under this system. Instead, regex saves the day by adding $ in the end of the string to be matched: grep -q ":$file2do"$.

  • Some updates done; please let further comment on the script go via git. Commented Jun 26, 2019 at 12:41
  • Thank you for introducing me into hashing. I believe that's the only thing I missed for making such a script come true. I did also branch your repo and make some change, and will keep working on that.
