      NAME
           sdiff - side-by-side difference program

      SYNTAX
           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 only exists in file1, a > in the
           gutter if the line only exists in file2, and a | for lines
           that are different.

           For example:

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

           The following options exist:

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

           -l         Only print 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;
                      where 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.
