|COMM(1)||General Commands Manual||COMM(1)|
commutility 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 options are as follows:
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.
commutility exits 0 on success, and >0 if an error occurs.
commutility conforms to IEEE Std 1003.1-2008 (“POSIX.1”).
The flag [
-f] is an extension to that
commcommand appeared in Version 4 AT&T UNIX.
