SDIFF(1)                                                              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 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

     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 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





                                                                        Page 1

SDIFF(1)                                                              SDIFF(1)



                        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.
