# This program replaces the original dd program and assumes that the actual dd program has been moved, in its same 
# directory, to the dd2 file.
# What it does is verify that no disk with the label $ LABELDISK is written directly with dd. 
# If no disk labeled $ LABELDISK is connected or no attempt is made to write directly to it, the original dd2 program 
# is called with all the parameters, just as they were passed to it. This program is not immune to code injection. 


# Este programa reemplaza al programa dd original y asume que el verdadero programa dd se ha movido, en su mismo directorio, al archivo dd2.
