# This example script is used for testing the reading of a file.
# It will attempt to connect to a specific share and then read a specified file.
# Example usage: ruby read_file.rb 192.168.172.138 msfadmin msfadmin TEST_SHARE short.txt
# This will try to connect to \\192.168.172.138\TEST_SHARE with the msfadmin:msfadmin credentials
# and read the file short.txt
