I often end up with duplicate files with same content, but with same or different names while doing the literature study. How to find and delete the duplicate files from terminal? How to just move them to bin and recover later if necessary and how to delete them permanently?

    Does this help? How to find ONLY duplicate files that have different names? I posted two answers there, one with a flexible script that offers many options to filter, the other with a relatively simple Bash one-liner that just finds all duplicates by content. – Byte Commander Oct 14 '20 at 9:08
  • The one-lines seems to be easy to remember and can be used anywhere across all my systems where I can not have root permissions. – Srinivasarao Bukkuru Oct 14 '20 at 11:20
