So, to recover plain text data one can simply do a brute force grep of the
filesystem to find a unique string in the deleted file. My Fortran files all
contained a unique string, the name of a module I wrote called
“auxpf_filter.” Thus, using the following command I was able to eventually
find the files I needed.


grep --binary-files=text -300 "auxpf_filter" /dev/hda4 > output.txt
