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



                                                                1

sdiff(1)                 USER COMMANDS                   sdiff(1)



                         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.
