This tool will be useful probably only for advanced linux users, so there is no package for it. Maybe someday I'll create script that automates instalation, but for now:

1. Clone this repo: git clone https://github.com/Q-back/ls-rescue/
2. Add alias to your .bashrc or whatever your distro uses:

• nano ~/.bashrc
• add (e.g to the end of file) line: alias ls-rescue="path/to/ls-rescue.py"

3. Enjoy.

• To diff two ls outputs from files

  • save your ls before and after your mistake to 2 separate files
  • run ls-rescue -f ls1_file ls2_file.

• To diff two ls outputs normally

  • run ls-rescue
  • input first ls output
  • input second ls output

  You'll see what changed.
