For example say suppose these were my files:

file1:

Code:
 
Blocks Reserved,CELL,1A,,,,AGBLK,0,0,1,CELL,1A,,,,ERICSSON,GSM,07B
Blocks Reserved,CELL,1B,,,,AGBLK,2,2,1,CELL,1B,,,,ERICSSON,GSM,07B
Blocks Reserved,CELL,1C,,,,AGBLK,3,3,1,CELL,1C,,,,ERICSSON,GSM,07B

file2:

Code:
 
Blocks Reserved,CELL,1A,,,,AGBLK,5,5,1,CELL,1A,,,,ERICSSON,GSM,07B
Blocks Reserved,CELL,1B,,,,AGBLK,2,2,1,CELL,1B,,,,ERICSSON,GSM,07B
Blocks Reserved,CELL,1C,,,,AGBLK,3,3,1,CELL,1C,,,,ERICSSON,GSM,07B

Then I want my result file to display the original line from file1 and below that the line that changed in file2:

Code:
 
Blocks Reserved,CELL,1A,,,,AGBLK,0,0,1,CELL,1A,,,,ERICSSON,GSM,07B
Blocks Reserved,CELL,1A,,,,AGBLK,5,5,1,CELL,1A,,,,ERICSSON,GSM,07B
