Duplicates in file

[mrcuser]

Hi!

I have 2 files,that contain a list of volumes:

1st has volumes in filesystem that are readable
2nd has volumes in the filesytem it think are unavailable

First file is called readable
Second file is called unavailable

is there a command that does the opposite of diff to pick out any duplication in both files ?

 

[p5wizard]

[tt]uniq -d /path/to/file[/tt]

prints duplicated lines in one file

[tt]comm -3 /path/to/file1 /path/to/file2[/tt]

prints lines that appear in both files


HTH,
