 diff options fileA fileB
   
 DESCRIPTION
 diff is used to compare the contents of two text files. Diff3
 compares three files.  Lines that are the same in all files are not
 printed.  Lines that are different are shown with arrows.  Note that
 the arrow "points" at the file from which the line came:
   
 < Lines found in fileA, but not in fileB.
 > Lines found in fileB, but not in fileA.
