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 < 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  filename1
           and  filename2  are  copied to output. Sets of differ-
           ences, 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  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  con-
           catenated 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  environment variable.  If LC_ALL is set, its con-
     tents 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.
