OpenSolaris 2009.06 - man page for sdiff (opensolaris section 1)

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  gut-
       ter 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 identical.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  file-
		     name1  and  filename2 are copied to output. Sets of differences, as produced
		     by diff, are printed; where a set of differences share a common gutter char-
		     acter. 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 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 concatenated 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_COLLATE, 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 envi-
       ronment 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 char-
		    acters for that locale.

ATTRIBUTES
