DC one liners always seem like the most arcane bit of magic (to the uninitiated like me). E.g. dc -e '_640320[0ksslk3^16lkd12+sk-lmlhd1+sh3^/smlxljsxll54514013

For those who are on NixOS and can’t find `dc`, it’s present in BusyBox. nix run nixpkgs#busybox -- dc -e '_640320[0ksslk3^16lkd12+sk*-lm*lhd1+sh3^/smlxlj*sxll545140134+dsllm*lxlnk/ls+dls!=P]sP3^sj7sn[6sk1ddshsxsm13591409dsllPx10005v426880*ls/K3-k1/pcln14+snlMx]dsMx'

    Haha, thanks! I had completely forgotten about `nix2` commands. I’ll try to remember this one!

      nix-locate is actually a third-party command, shipped with nix-index: https://github.com/nix-community/nix-index https://github.com/nix-community/nix-index make sure to check out the pregenerated databases, they're very convenient

  Oh, you are correct. Hn ate the formatting. The example is stolen from wikipedia. Lets try that again: dc -e '_640320[0ksslk3^16lkd12+sk*-lm*lhd1+sh3^/smlxlj*sxll545140134+dsllm*lxlnk/ls+dls!=P]sP3^sj7sn[6sk1ddshsxsm13591409dsllPx10005v426880*ls/K3-k1/pcln14+snlMx]dsMx'

Cool, will save this. People should run this if they do not know what it does.
