👀 Using

✅ Requirements

• OS¹
  • 🟡 Linux: GNU, MinGW and Termux only; musl² not supported
  • 🟢 macOS: Compatible with built-in version of Bash (3.2)
  • 🟡 Windows: MinGW (Cygwin, Git Bash, MSYS2, etc.) and WSL (see Linux caveats above)
    • This repository does not provide a native version for Windows
  • 🟢 BSD: FreeBSD, NetBSD and OpenBSD; other non-detected BSDs should work (see ¹)
  • 🟢 Haiku: Yes, really
  • 🔴 Solaris: Has issues; low priority
• Bash³: 3.x or later
• Packages
  • curl
  • ExifTool (exiftool) (optional: set ATFILE_SKIP_NI_EXIFTOOL=1 to ignore)
  • file (only on *BSD, macOS, or Linux)
  • GnuPG (gpg) (optional: needed for upload-crypt, fetch-crypt)
  • jq
  • MediaInfo (mediainfo) (optional: set ATFILE_SKIP_NI_MEDIAINFO=1 to ignore)
  • md5sum (optional: set ATFILE_SKIP_NI_MD5SUM=1 to ignore)
    • Both GNU and BusyBox versions supported
  • websocat (optional: needed for stream)
• PDS: Bluesky PDS
  • Other PDSs (such as millipds) remain untested, but if they implement standard com.atproto.* endpoints, there should be no reason these won't work
  • Filesize limits cannot be automatically detected. By default, this is 50MB
    • To change this on Bluesky PDS, set PDS_BLOB_UPLOAD_LIMIT=<bytes>
    • If the PDS is running behind Cloudflare, the Free plan imposes a 100MB upload limit
    • This tool, nor setting a higher filesize limit, does not workaround video upload limits on Bluesky. Videos are served via a CDN, and adding larger videos to post records yields errors on the app
• ATProto account
  • bsky.network (*.bsky.social) accounts supported
    If you can, limit the amount of files you upload to Bluesky's servers. It's a miracle this even works with, what's currently, an entirely free service. Heed the copyright warning too: do not upload copyrighted files.
  • did:web is supported!
    (Seriously, it ain't hard)

• ¹ You can bypass OS detection in one of two ways:
  • Set ATFILE_SKIP_UNSUPPORTED_OS=1
    Be careful! There's a reason some OSes are not supported
  • Set ATFILE_FORCE_OS=<os>
    This overrides the OS detected. Possible values:
    • BSD: bsd-freebsd, bsd-netbsd, bsd-openbsd
    • Linux: linux, linux-mingw, linux-musl, linux-termux
    • Other: haiku, macos, solaris, unknown
• ² musl-powered distros do not use GNU/glibc packages, and have problems currently
  • Known musl distros: Alpine, Chimera, Dragora, Gentoo (musl), Morpheus, OpenWrt, postmarketOS, Sabotage, Void
  • Bypassing OS detection (see ¹) will work, but dates will not be handled correctly
• ³ As long as you have Bash installed, running from another shell will not be problematic (#!/usr/bin/env bash forces Bash)
