NAME
        sdiff  -  find  differences  between  two  files and merge
        interactively
 
SYNOPSIS
        sdiff -o outfile [options] from-file to-file
 
DESCRIPTION
        The sdiff command merges two files and interactively  out­
        puts the results to outfile.
 
        If from-file is a directory and to-file is not, sdiff com­
        pares the file in from-file whose file name is that of to-
        file,  and vice versa.  from-file and to-file may not both
        be directories.
 
        sdiff options begin with -, so normally from-file and  to-
        file  may not begin with -.  However, -- as an argument by
        itself treats the remaining arguments as file  names  even
        if they begin with -.  You may not use - as an input file.
 
        sdiff without -o (or  --output)  produces  a  side-by-side
        difference.     This   usage   is   obsolete;   use   diff
        --side-by-side instead.
 
    Options
        Below is a summary of all of the options  that  GNU  sdiff
        accepts.   Each  option  has  two equivalent names, one of
        which is a single letter preceded by -, and the  other  of
        which is a long name preceded by --.  Multiple single let­
        ter options (unless they take an argument) can be combined
        into  a  single command line argument.  Long named options
        can be abbreviated to any unique prefix of their name.
 
        -a     Treat all files as text and compare  them  line-by-
               line, even if they do not appear to be text.
 
        -b     Ignore changes in amount of white space.
 
        -B     Ignore  changes  that  just  insert or delete blank
               lines.
 
        -d     Change the algorithm to perhaps find a smaller  set
               of  changes.   This  makes  sdiff slower (sometimes
               much slower).
 
        -H     Use heuristics to speed  handling  of  large  files
               that have numerous scattered small changes.
 
        --expand-tabs
               Expand  tabs  to  spaces in the output, to preserve
               the alignment of tabs in the input files.
 
        -i     Ignore changes in case; consider upper- and  lower-
               case to be the same.
 
        -I regexp
               Ignore  changes  that  just  insert or delete lines
               that match regexp.
 
        --ignore-all-space
               Ignore white space when comparing lines.
 
        --ignore-blank-lines
               Ignore changes that just  insert  or  delete  blank
               lines.
 
        --ignore-case
               Ignore  changes in case; consider upper- and lower-
               case to be the same.
 
        --ignore-matching-lines=regexp
               Ignore changes that just  insert  or  delete  lines
               that match regexp.
 
        --ignore-space-change
               Ignore changes in amount of white space.
 
        -l
        --left-column
               Print only the left column of two common lines.
 
        --minimal
               Change  the algorithm to perhaps find a smaller set
               of changes.  This  makes  sdiff  slower  (sometimes
               much slower).
 
        -o file
        --output=file
               Put  merged  output  into  file.   This  option  is
               required for merging.
 
        -s
        --suppress-common-lines
               Do not print common lines.
 
        --speed-large-files
               Use heuristics to speed  handling  of  large  files
               that have numerous scattered small changes.
 
        -t     Expand  tabs  to  spaces in the output, to preserve
               the alignment of tabs in the input files.
 
        --text Treat all files as text and compare  them  line-by-
               line, even if they do not appear to be text.
 
        -v
        --version
               Output the version number of sdiff.
 
        -w columns
        --width=columns
               Use an output width of columns.  Note that for his­
               torical reasons, this option is -W in diff,  -w  in
               sdiff.
 
        -W     Ignore horizontal white space when comparing lines.
               Note that for historical reasons, this option is -w
               in diff, -W in sdiff.

 DIAGNOSTICS
        An  exit  status  of  0 means no differences were found, 1
        means some differences were found, and 2 means trouble.
