When FILE1 or FILE2 (not both) is -, read standard input.
With no options, produce three-column output. Column one contains lines unique to FILE1, column two contains lines unique to FILE2, and column three contains lines common to both files.
- suppress column 1 (lines unique to FILE1)
- suppress column 2 (lines unique to FILE2)
- suppress column 3 (lines that appear in both files)
- check that the input is correctly sorted, even if all input lines are pairable
- do not check that the input is correctly sorted
- separate columns with STR
- output a summary
- -z, --zero-terminated
- line delimiter is NUL, not newline
- display this help and exit
- output version information and exit
Note, comparisons honor the rules specified by 'LC_COLLATE'.
- comm -12 file1 file2
- Print only lines present in both file1 and file2.
- comm -3 file1 file2
- Print lines in file1 not in file2, and vice versa.
