NAME
     sdiff - side-by-side difference program

SYNOPSIS
     sdiff [ options ... ] file1 file2

DESCRIPTION
     sdiff uses the output of diff(1) to produce a side-by-side
     listing of two files indicating those lines that are dif-
     ferent.  Each line of the two files is printed with a blank
     gutter between them if the lines are identical, a < in the
     gutter if the line only exists in file1, a > in the gutter
     if the line only exists in file2, and a | for lines that are
     different.

     For example:

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

OPTIONS
     The following options exist:

     -w  n               Use the next argument, n, as the width
                         of the output line.  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 the next argument, output, as the
                         name of a third file that is created as
                         a user-controlled merging of file1 and
                         file2.  Identical lines of file1 and
                         file2 are copied to output.  Sets of
                         differences, as produced by diff(1), 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 com-
                         mands:

     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
     on the end of the output file.
