Create a simple bash, perl or python script

Hey There, I have two files: File1: #DESCRIPTION NAME1 #SERVICE value1 #DESCRIPTION NAME2 #SERVICE value2 #DESCRIPTION NAME3 #SERVICE value3 File2: #DESCRIPTION NAME2 #SERVICE value5 I need all lines of File1 compared to file2 and should a match be found file1 would be updated with the #description and #service from file2. Looking fast resolution to this.
