If we had a Busybox for every platform, and you compiled your app for every platform, you could bundle it all as one compressed shell script. Not as cool as one binary that works everywhere, but much simpler. #!/usr/bin/env sh
set -eu
FILE="${OS:-$(uname -s)}/${ARCH:-$(uname -p)}/${MACH:-$(uname -m)}/exe"
unzip -d "${TMPDIR:-/tmp}" -X -b -o "$0" "$FILE"
[ $? -gt 1 ] || exec "${TMPDIR:-/tmp}/$FILE"
echo "$0: Error: could not execute '$FILE'" ; exit 126
