comm
utility reads file1 and
file2, which should be sorted lexically, and produces
three text columns as output: lines only in file1; lines
only in file2; and lines in both files.
The filename ``-'' means the standard input.
The following options are available:
-1
-2
-3
-f
Each column will have a number of tab characters prepended to it equal to the number of lower numbered columns that are being printed. For example, if column number two is being suppressed, lines printed in column number one will not have any tabs preceding them, and lines printed in column number three will have one.
comm
assumes that the files are lexically
sorted; all characters participate in line comparisons.
comm
utility exits 0 on success,
and >0 if an error occurs.
comm
utility conforms to IEEE Std
1003.2-1992 (“POSIX.2”).
