sdiff(1)                         User Commands                        sdiff(1)



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 <&lt; in the gutter if the line appears only in filename1, a >&gt;
       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 file-
                       name2 are copied to output.  Sets  of  differences,  as
                       produced  by  diff, are printed; where a set of differ-
                       ences 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  com-
                       mands:


                       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.



USAGE
       See  largefile(5)  for  the  description  of the behavior of sdiff when
       encountering files greater than or equal to 2 Gbyte ( 2**31 bytes).

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(5)) 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.
