I am sorry for not stating my requirement properly , We are trying to accomplish incremental load of data by comparing two files

File 1
Code:
 id   | text       | email id 
---------------------------------
89564|this is line 1 | xyz@sample.txt
985384|this is line 14 | abc@sample.txt
657342|this is line 3 | def@sample.txt

File 2

Code:
 id   | text       | email id 
---------------------------------
89564|this is line 1 | xyz@sample.txt
985384|this is line 2 | abc@sample.txt


I would like output by comparing above two files which should display below results
Desired Output:
-------------------
Code:
 id   | text       | email id 
---------------------------------
89564|this is line 1 | xyz@sample.txt
985384|this is line 2 | abc@sample.txt | modified (Note :  second column got modified ) 
657342|this is line 3 | def@sample.txt | deleted

Here we are trying to compare two files and if we don't find a record in file 2 based on column 1 ( primary key ) we treat that entry as deleted and we generate a new file with its operational code(in this case deleted). Similarly we if we find record in both the files ( file 1 and file2) we would still have that record in file 3 ,and for modified if we see any column modifies in file 2 we add the entry as modified .
