Hi all,

I have two files, both have a list of 6 digit values. I want to compare them and output the values that match up. The lines in each file are not supposed to contain the same value (in other words, line 1 in each file may or may not contain the value 000001, and so on).

Thanks for the help!

What is your goal here? For example, do you want to:

1. Show where the same values exist in each file and relative position
example: line3 file1 is the same as line 227 file2

2. Count the number of occurrences of same values in file1 + file2
example: 201622 occurs 1 time in both files
344702 occurs 2 times in both files
001010 occurs 2 times in both files

3. TOTAL the number of times the same value exists in each file
example: (based on #2 above) file1 + file2 have a total of 5 occurrences of the same value.

4. Query against a specific value to see if (position agnostic) it appears in both files.
example: does 001010 exist at all in file1, file2

You might wish to consider reading up on three useful utilities one or more of which may be of assistance to you.
- comm
- diff
- sort

There is a Perl script or two out there which would accomplish one or more of the example goals I wondered about above.

Bob, thanks for the reply.

I am trying to achieve #4. I want to know which values from file 1 match file 2. I'll check out those commands again, but I didn't seem to see how they could be helpful.

Thanks!

jeez, simple as that...comm worked. I actually hadn't looked at that one. Thanks bob!
