NAME
     sdiff - print file differences side-by-side

SYNOPSIS
     sdiff [ options ] file1 file2

DESCRIPTION
     sdiff uses the output of the diff command to produce a
     side-by-side listing of two files indicating lines that are
     different.  Lines of the two files are printed with a blank
     gutter between them if the lines are identical, a < in the
     gutter if the line appears only in file1, a > in the gutter
     if the line appears only in file2, and a | for lines that
     are different.  For example:

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

     Valid options are:

     -w  n      Use the 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 argument output as the name of a third
                file that is created as a user-controlled merge
                of file1 and file2.  Identical lines of file1 and
                file2 are copied to output.  Sets of differences,
                as produced by diff, 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 ident-
                         ical 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 to the end of the output file.

INTERNATIONAL FUNCTIONALITY
     sdiff can process files containing characters from supple-
     mentary code sets.

     For the -wn option, the width specified by n is in columns,
     not characters.  Multi-column characters which across the
     right margin of a line are displayed as ASCII spaces.
