sdiff(1)         (Directory and File Management Utilities)         sdiff(1)


   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 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 to the end of the output file.
