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.
