Looks like there is both an ARM and x86 version according to the docs. Probably need two different binaries, but you still get cross-OS for each architecture.

It's a single binary, cross-OS, cross-arch. Go to https://cosmo.zip/pub/cosmos/bin/ https://cosmo.zip/pub/cosmos/bin/ and download an executable, like https://cosmo.zip/pub/cosmos/bin/basename https://cosmo.zip/pub/cosmos/bin/basename . % curl -O https://cosmo.zip/pub/cosmos/bin/basename % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 663k 100 663k 0 0 440k 0 0:00:01 0:00:01 --:--:-- 441k % chmod +x basename On macOS with an M1: % arch arm64 % sha256sum basename 2e4cf8378b679dd0c2cdcc043bb1f21eaf464d3c3b636ed101fbc5e3230eb5fb basename % file ./basename ./basename: DOS/MBR boot sector; partition 1 : ID=0x7f, active, start-CHS (0x0,0,1), end-CHS (0x3ff,255,63), startsector 0, 4294967295 sectors % ./basename /dev/null.txt null.txt On FreeBSD with an amd64: % uname -sm FreeBSD amd64 % sha256sum basename 2e4cf8378b679dd0c2cdcc043bb1f21eaf464d3c3b636ed101fbc5e3230eb5fb basename % file basename basename: DOS/MBR boot sector; partition 1 : ID=0x7f, active, start-CHS (0x0,0,1), end-CHS (0x3ff,255,63), startsector 0, 4294967295 sectors % ./basename /dev/null.pdf null.pdf

  Kind of. It can be read as a single binary, some supported systems will do that. In others, the executable is first parsed as a shell script. There's definitely more to it than a single binary.

    Reminds me of a cool tool I once used, uudecode.com, which was a DOS binary that only used 7-bit characters and could decode uuencoded (base64 predecessor) files. Was useful for getting attachments through e-mail in the face of all kinds of filters.
