Display iOS Provisioning Profile (.mobileprovision) Details With Command Line Ruby Utility

profname.rb

#!/usr/bin/env ruby

# -----------------------------------------------------
# Usage: profname.rb /path/to/profiles/directory
# If no arguments are passed in, the default provisioning profiles directory
# on macOS is used: ~/Library/MobileDevice/Provisioning Profiles
#
# Script expects a directory, not a single file. Use grep on the command
# line to locate specific details.

# Ref: Got this from https://gist.github.com/pdsarin/5377836 . Modified
# it to take a file handle instead of a file path so the file doesn't
# get opened/closed on every property access
