✨ FINDDUP(1) ✨

okay so bestie, this is finddup — a Perl situation that hunts down identical files and then, like, does stuff with them 💅 it lives in the Perl corner of your manual, so you already know it's giving script-kid-with-a-plan energy 🐚

🌸 NAME 🌸

finddup — find identical files and do something with them 🦋

🎀 SYNOPSIS 🎀

Usage:

finddup [options...]
  • --man — the manpage 📖 (yes, the thing you're reading, very meta of her)
  • -h, --help — a short help, a lil snack-sized version 🍓
  • --version — the version (CVS) of the program, for the nosy girlies 👀
  • -n, --noaction — do just nothing, just print out (implies -v) 🙈 the delulu mode: she talks a big game and then touches nothing
  • -v, --verbose — just what the name says, she will Not be quiet about it 🗣️
  • -q, --quiet — be quiet 🤫
  • -l, --link — link the identical files together 🔗
  • -o, --oldresult — use the old output of this script 📜
  • -i, --ignore-perms — don't check that file owner and permissions match 🚫🔐
  • -d, --dir — define the dir to check (you may specify more than one) 📁✨

💖 DESCRIPTION 💖

finddup searches the working directory — and every file below it, as long as they're on the same partition — for duplicate files 🔍

finddup can, optionally, hardlink such files to save space 🫶

Files of size 0 will not be reported or hardlinked, because that might give problemes later 💀 (yes, problemes, she said what she said)

This is a complete rewrite of the finddup in perl to handle several issues, and the way she fixed them all? obsessed 😭:

  • Allow spaces and other characters in filenames 🌈
  • be faster ⚡
  • include nodup in same script 🧚
  • Handle files that already have other hardlinks in the same tree 🌳
  • Several improvements ✨
Bestie, heads up: if you start this script as nodup or nodup.pl, it will act exactly like it was started with the options --link and --oldresult 👑 no cap.
