I have iPython Notebook through Anaconda. I accidentally deleted an important notebook, and I can't seem to find it in trash (I don't think iPy Notebooks go to the trash).

Does anyone know how I can recover the notebook? I am using Mac OS X.

Thanks!

This is bit of additional info on the answer by Thuener,

I did the following to recover my deleted .ipynb file.

  1. The cache is in ~/.cache/chromium/Default/Cache/ (I use chromium)
  2. used grep in binary search mode, grep -a 'import math' (replace search string by a keyword specific in your code)
  3. Edit the binary file in vim (it doesn't open in gedit)
    • The python ipynb should file start with '{ "cells":' and
    • ends with '"nbformat": 4, "nbformat_minor": 2}'
    • remove everything outside these start and end points
  4. Rename the file as .ipynb, open it in your jupyter-notebook, it works.
