NAME
       sdiff - print differences between two files side-by-side

SYNOPSIS
       sdiff [-l] [-s] [-o output] [-w n] filename1 filename2

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 filename1, a >
       in  the gutter if the line appears only in filename2, and a | for lines
       that are different. (See the EXAMPLES section below.)

OPTIONS
       -l           Print only the left side of any  lines  that  are  identi‐
                    cal.to


       -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  filename1  and
                    filename2.  Identical lines of filename1 and filename2 are
                    copied to output. Sets  of  differences,  as  produced  by
                    diff, are printed; where a set of differences share a com‐
                    mon gutter character. After printing each set  of  differ‐
                    ences,  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 concate‐
                    nated to the end of the output file.


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


EXAMPLES
       Example 1 An example of the sdiff command.




       A sample output of sdiff follows.




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


ENVIRONMENT VARIABLES
       If  any of the LC_* variables ( LC_CTYPE, LC_MESSAGES, LC_TIME, LC_COL‐
       LATE, LC_NUMERIC, and LC_MONETARY ) (see environ(7)) are not set in the
       environment,  the  operational behavior of sdiff for each corresponding
       locale category is determined by the  value  of  the  LANG  environment
       variable.  If LC_ALL is set, its contents are used to override both the
       LANG and the other LC_* variables. If none of the  above  variables  is
       set in the environment, the "C" locale determines how sdiff behaves.

       LC_CTYPE    Determines  how  sdiff handles characters. When LC_CTYPE is
                   set to a valid value, sdiff can display and handle text and
                   filenames containing valid characters for that locale.
