' file1 file2 > file3

Using only line 1 in example for file1 and file2.
rdrtx1 - This works perfect and is exactly what I was looking for. I did find somethings that I would like to see if they could be added and it's my fault for thinking of them after the fact.

Is there a way to only output into file3 the results where there were differences? If fields 2,3,4,5,or 6 are the same they do not need to be outputted into file3.

uniq

UNIQ(1) 						    BSD General Commands Manual 						   UNIQ(1)

NAME

     uniq -- report or filter out repeated lines in a file

SYNOPSIS

     uniq [-cdu] [-f fields] [-s chars] [input_file [output_file]]

DESCRIPTION

     The uniq utility reads the standard input comparing adjacent lines, and writes a copy of each unique input line to the standard output.  The
     second and succeeding copies of identical adjacent input lines are not written.  Repeated lines in the input will not be detected if they are
     not adjacent, so it may be necessary to sort the files first.

     The following options are available:

     -c      Precede each output line with the count of the number of times the line occurred in the input, followed by a single space.

     -d      Don't output lines that are not repeated in the input.

     -f fields
	     Ignore the first fields in each input line when doing comparisons.  A field is a string of non-blank characters separated from adja-
	     cent fields by blanks.  Field numbers are one based, i.e. the first field is field one.

     -s chars
	     Ignore the first chars characters in each input line when doing comparisons.  If specified in conjunction with the -f option, the
	     first chars characters after the first fields fields will be ignored.  Character numbers are one based, i.e. the first character is
	     character one.

     -u      Don't output lines that are repeated in the input.

     If additional arguments are specified on the command line, the first such argument is used as the name of an input file, the second is used
     as the name of an output file.

     The uniq utility exits 0 on success, and >0 if an error occurs.

COMPATIBILITY

     The historic +number and -number options have been deprecated but are still supported in this implementation.

SEE ALSO

     sort(1)

STANDARDS

     The uniq utility is expected to be IEEE Std 1003.2 (``POSIX.2'') compatible.
