       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

             sdiff processes supplementary code set characters in files
             according to the locale specified in the LC_CTYPE environment
             variable [see LANG on environ(5)].

             Valid options are:

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

             -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:

      sdiff(1)                                                    sdiff(1)


                       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.
