and a lil PSA, bestie: this PSL is maintained by the Mozilla Foundation 👑 and they update it a few times per month. you are politely requested to download it no more than once per day. do NOT be the greedy one, it's giving rude fr fr 🙈

🌈 Options 🌈

dmarc_update_public_suffix_list [ --dryrun --help ]

look at the lil menu, so cute:

  • dryrun — shows you what it would do without ever overwriting your file. peek but don't touch energy 👀
  • random — throws in a random delay to spread the server load around. intended for when you're running it from crontab so everybody isn't showing up at the same second like it's a drop 🎀
  • config-file — alternate config file path, for when you're not living at the default spot
  • help — prints this syntax guide, literally the manual in your terminal

💜 EXAMPLES 💜
