Sideload IPA on jailbroken iOS device (like AppSync Unified, the installed apps will only work when the device is in jailbroken state)

sideload.sh

#!/bin/bash

if (( EUID != 0 )); then
  printf 'This script must be run as root.\n' >&2
  exit 1
fi

if [[ $1 != *.ipa ]]; then
  printf 'Usage: %s file.ipa\n' "$0" >&2
  exit 1
fi

rm -rf Payload

unzip "$1"
pushd Payload
dir=(*.app)
mv "${dir[0]}" /Applications/
uicache -p "/Applications/${dir[0]}" -r
popd
rm -rf Payload
