With persistence (recommended)

Writes the ISO and keeps your files and settings between boots in the space left over. Replace /dev/sdX with your USB stick (check with lsblk).

$ git clone --depth 1 https://github.com/Null0Grid/null-os && \
  sudo null-os/tools/make-usb.sh nullos-1.2.1-trixie-amd64.iso /dev/sdX

With dd

A plain copy, without persistence. balenaEtcher or Rufus on Windows also work.

$ sudo dd if=nullos-1.2.1-trixie-amd64.iso of=/dev/sdX bs=4M status=progress conv=fsync
