warpbox: upload files to Warpbox from the terminal

USAGE:
  warpbox [options] <file> [file ...]

OPTIONS:
  -p, --password <pw>       Require a password to view/download the box
  -e, --expiry <dur>        Lifetime before expiry: 30m, 6h, 2d, 1w (or bare minutes)
  -n, --max-downloads <n>   Expire after N downloads
  -o, --obfuscate           Hide file names/counts until unlocked (needs --password)
      --host <url>          Warpbox server to upload to (or set WARPBOX_HOST)
      --auth <token>        API token (prefer the WARPBOX_TOKEN env var, see AUTH)
      --auth-file <path>    Read the API token from a file (safer than --auth)
      --json                Print the full JSON response instead of just the URL
  -h, --help                Show this help

AUTH:
  Uploads are anonymous unless a token is supplied. The most secure option is the
  WARPBOX_TOKEN environment variable, so the token never lands in your shell
  history or the process list:

    export WARPBOX_TOKEN=wbx_your_token
    warpbox ./photo.png

  Create a token under Account, Access tokens. Avoid --auth on shared machines.

EXAMPLES:
  warpbox ./report.pdf
  warpbox --password 123 --expiry 2d ./first_file.zip ./whatever.png ./all_*_photos.jpg
  warpbox --max-downloads 5 --json ./build.zip
