I have two files that contain account names. I need to compare them and get a print out of what is in file2 that is not in file1. So, if jjones is in both, I don't care. If jsmith is in file1 and not file2, again, I don't care. However, if jjohnson is in file2 but not in file1 I want to know about it.

I've been playing around with these commands and I can't seem to get it to give me the correct information.

If i do comm -1 -3 file1 file2 it seems to just print out everything that is in file2.

Am I dont something wrong?

Please help...
 
comm wants the input files to be sorted.

$ sort file1 > file1.tmp
$ sort file2 > file2.tmp
$ comm -1 -3 file1.tmp file2.tmp

Thanks for the reply. But that just gives me what is in file2 still.

Me confused....

EDIT - okay, I just made two test files with very little in them, but a few differences. I did the comm -1 -3 file1 file2 > file3 -- and file3 was exactly as it should be.

Could I be having an issue with how the files are formatted before the comm command is used?
 
You did compare the sorted files, right? The commands I gave you work fine for some small test files. Can you provide a sample line from one of the files (or a fake line that looks the same)?
