A little uninstall script I wrote to uninstall android apps via adb

android-uninstall.rb

#!/usr/bin/env ruby

def get_packages(prefix)
  pkgs = []
  s = `adb shell pm list packages #{prefix}`
  s.each_line do |line|
    next unless line.start_with?("package:")
    pkgs << line.split(":")[1]
  end
  pkgs
end

def uninstall_package(pkg)
  `adb uninstall #{pkg}`
end

def usage
  puts "USAGE: #{__FILE__} package"
  puts "Example: #{__FILE__} org.catrobat"
end

if ARGV.length < 1
  puts usage
  exit 1
end

pkgs = get_packages(ARGV[0])
pkgs.each do |pkg|
  print "uninstalling " + pkg
  puts uninstall_package(pkg)
end
