Shell Programming and Scripting

@Scrutinizer : Sorry once again.. The requirement is file1.txt and file2.txt may contain differences in data. But here i am not looking for the difference.. I will atke the first 2 key fields like below

file 1.txt

Code:

1003|A|hyd|1|che
1004|B|che|2|gun
1004|A|kin|3|king
1005|C|opt|4|opr

file2.txt

Code:

1003|A|hyd|1|che
1004|B|che|2|gun
1005|C|opt|5|or

Expected Output :

Code:

1004|A|kin|3|king

The first two fields are static , i want to check if file1.line1.field1 and file1.line1.field2 present in file2. if it is not present then print the file1.line1 in the output.

in the example above file1.line3.field1 is not prsent in file2 . so the output should be file1.line3.field1

Please look into this.. if you have any additional information please let me know .

Try something like this:

Code:

awk -F\| 'NR==FNR{A[$1 FS $2]; next}!($1 FS $2 in A)' file2 file1

Thank you so much @Scrutinizer its working as per requirement
