  NAME

    sdiff - Runs a side-by-side difference command

  SYNOPSIS

    sdiff [flag ... ] file1 file2

  FLAGS

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

    -l          Only display the left side of any lines that are identical.

    -s          Do not display 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, are
                displayed; where a set of differences share a common gutter
                character.  After displaying each set of differences, the
                sdiff command prompts the user with a % and waits for one of
                the following user-typed commands:

                l     Appends the left column to the output file

                r     Appends the right column to the output file

                s     Turn on silent mode; do not display identical lines

                v     Turns off silent mode

                e l   Calls the editor with the left column

                e r   Calls the editor with the right column

                e b   Calls the editor with the concatenation of left and
                      right

                e     Calls the editor with a zero length file

                q     Exits from the command

                Upon exiting from the editor, the resulting file is
                concatenated on the end of the output file.

  DESCRIPTION

    The sdiff command uses the output of diff to produce a side-by-side

    listing of two files indicating those lines that are different.  Each line
    of the two files is displayed 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


  EXAMPLES

    1.  To display, in 80-column lines, only those lines that differ between
        fileA and fileB:

        sdiff -w 80 -s fileA fileB


    2.  To interactively create outfile from the differences between fileA and
        fileB:

        sdiff -o outfile fileA fileB


    3.  To display the differences between fileA and fileB with identical
        lines displayed only in the left column:

        sdiff -l fileA fileB


  DIAGNOSTICS

    cannot open file
           An input file did not have read permission or does not exist.

    Cannot open output file
           The file given for the -o could not be opened in append mode.
           Check the permissions on the directory.

  EXIT VALUES

    The sdiff command exits with a nonzero value if an error occurs.
