rmlint

Identify duplicate files or directories, and other filesystem issues. More information: https://rmlint.readthedocs.io/en/latest/rmlint.1.html.

• Check a directory for duplicates, empty files, and other issues:
  rmlint {{path/to/directory}}
• Delete duplicate files found by an execution of rmlint:
  ./rmlint.sh
• Find duplicate directory trees:
  rmlint --merge-directories {{path/to/directory}}
• Mark files at lower path [d]epth as originals:
  rmlint --rank-by={{d}} {{path/to/directory}}
• Mark files with shortest name [l]ength as originals:
  rmlint --rank-by={{l}} {{path/to/directory}}
• Find only duplicates that have the same filename in addition to the same contents:
  rmlint --match-basename {{path/to/directory}}
• Find all duplicates with the same extension:
  rmlint --match-extension {{path/to/directory}}
