sdiff(1)                         DG/UX 5.4.2                        sdiff(1)


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 different.  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 exists only in
       file1; a > in the gutter if the line exists only in file2; and a |
       for lines that are different.

       For example:

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

       Options are:

       -w n         Use the next 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 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; 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 on the end of the output file.

   International Features
       sdiff can process files containing characters from supplementary code
       sets.

       Option:

       -wn    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.
