Appify shell script creates macOS app bundle from the script. It works on all major macOS X versions on PowerPC, Intel or ARM architectures.
#!/usr/bin/env bash APPNAME=${2:-$(basename "${1}" '.sh')}; DIR="${APPNAME}.app/Contents/MacOS"; if [ -a "${APPNAME}.app" ]; then echo "${PWD}/${APPNAME}.app already exists :("; exit 1; fi; mkdir -p "${DIR}"; cp "${1}" "${DIR}/${APPNAME}"; chmod +x "${DIR}/${APPNAME}"; echo "${PWD}/$APPNAME.app";
Copy it to the /usr/local/bin/appify and chmod +x /usr/local/bin/appify
appify <shell script.sh> <app bundle name>
