NAME
     sdiff - side-by-side difference program

USAGE
     sdiff [ options ... ] file1 file2

DESCRIPTION
     Sdiff uses the output of diff(1) to produce a side-by-side
     listing of two files to indicate those lines which differ.
     Each line of the two files is printed with a blank gutter
     between them if the lines are identical, a less-than charac-
     ter (<) in the gutter if the line only exists in file1, a
     greater-than character (>) in the gutter if the line only
     exists in file2, and a pipe character (|) for differing
     lines.

     The following illustrates the use of these characters:

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

OPTIONS
     -w  n     Use the next argument, n, as the width of the out-
               put line.  The value of n must be greater than 20.
               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 output as the name of a third file created as
               a user-controlled merging of file1 and file2.
               Copy identical lines of file1 and file2 to output.
               Print sets of differences, as produced by diff(1),
               where a set of differences share a common gutter
               character.  After printing each set of differ-
               ences, prompt the user with a percent sign (%) and
               wait for one of the following user-typed commands:

                        l    Append the left column to the output
                             file.

                        r    Append the right column to the out-
                             put 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 concatena-
                             tion of left and right.

                        e    Call the editor with a zero length
                             file.

                        q    Exit from the program.

                On exit from the editor, concatenate the result-
                ing file on the end of the output file.
