これは何？

Caligula is a terminal user interface for burning disk images, a friendlier alternative to running dd by hand. It lists attached disks with their size and hardware model, so you can pick the target visually instead of typing device paths from memory. Before writing, it asks for confirmation to reduce the risk of overwriting the wrong disk.

The tool can decompress input images in gz, bz2, xz, lz4 and zst formats, and it can validate an image against a hash such as md5, sha1 or sha256 before burning. It shows a live write-speed graph and verifies the disk after writing. If the current user lacks permission to write to the device, it can re-run the operation through sudo, doas or su.

Caligula is written in Rust and is published as a single binary under five megabytes. It is invoked with `caligula burn <IMAGE>`, and it can run non-interactively with flags for scripting. Linux x86_64 is the best-supported platform, with macOS builds available but with limited testing.

主な機能

  • 01Lists attached disks with size and hardware model information
  • 02Decompresses gz, bz2, xz, lz4 and zst input images
  • 03Validates images against md5, sha1, sha256 and other hashes before writing
  • 04Verifies the disk after writing
  • 05Asks for confirmation before erasing a disk, with a force flag to skip it
  • 06Escalates privileges with sudo, doas or su when needed

ユースケース

  • Writing a Linux installer ISO to a USB flash drive
  • Flashing a Raspberry Pi or other OS image to an SD card
  • Replacing ad-hoc dd commands in scripts or workflows that need safer confirmation
