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 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 to the end of the output file.
