     NAME
          sdiff - side-by-side difference program

     SYNOPSIS
          sdiff [ options ... ] file1 file2

     DESCRIPTION
          Sdiff uses the output of diff(1) to produce a side-by-side
          listing of two files indicating those lines that are
          different.  Each line of the two files is printed with a
          blank gutter between them if the lines are identical, a < in
          the gutter if the line exists only in file1; a > in the
          gutter if the line exists only in file2; and a | for lines
          that are different.

          For example:

                          x    |    y
                          a         a
                          b    <
                          c    <
                          d         d
                               >    c

          Options are:

          -w  n        Use the next argument, n, as the width of the
                       output line.  The default line length is 130
                       characters.

          -l           Print only the left side of any lines that are
                       identical.

          -s           Do not print identical lines.

          -o  output   Use the next argument, output, as the name of a
                       third file that is created as a user-controlled
                       merging of file1 and file2.  Identical lines of
                       file1 and file2 are copied to output.  Sets of
                       differences, as produced by diff(1), are
                       printed; a set of differences share a common
                       gutter character.  After printing each set of
                       differences, sdiff prompts the user with a %
                       and waits for one of the following user-typed
                       commands:

                             l    Append the left column to the output
                                  file

                             r    Append the right column to the
                                  output file

                             s    Turn on silent mode; do not print
                                  identical lines

                             v    Turn off silent mode

                             e  l Call the editor with the left column

                             e  r Call the editor with the right
                                  column

                             e  b Call the editor with the
                                  concatenation of left and right

                             e    Call the editor with a zero length
                                  file

                             q    Exit from the program

                     On exit from the editor, the resulting file is
                     concatenated on the end of the output file.
