Options to `sdiff'
==================

   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 letter 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.  Note: Binary.

`-b'
     Ignore changes in amount of white space.  Note: White Space.

`-B'
     Ignore changes that just insert or delete blank lines.  Note:
     Blank Lines.

`-d'
     Change the algorithm to perhaps find a smaller set of changes.
     This makes `sdiff' slower (sometimes much slower).  Note: diff
     Performance.

`-H'
     Use heuristics to speed handling of large files that have numerous
     scattered small changes.  Note: diff Performance.

`--expand-tabs'
     Expand tabs to spaces in the output, to preserve the alignment of
     tabs in the input files.  Note: Tabs.

`-i'
     Ignore changes in case; consider upper- and lower-case to be the
     same.  Note: Case Folding.

`-I REGEXP'
     Ignore changes that just insert or delete lines that match REGEXP.
     Note: Specified Folding.

`--ignore-all-space'
     Ignore white space when comparing lines.  Note: White Space.

`--ignore-blank-lines'
     Ignore changes that just insert or delete blank lines.  Note:
     Blank Lines.

`--ignore-case'
     Ignore changes in case; consider upper- and lower-case to be the
     same.  Note: Case Folding.

`--ignore-matching-lines=REGEXP'
     Ignore changes that just insert or delete lines that match REGEXP.
     Note: Specified Folding.

`--ignore-space-change'
     Ignore changes in amount of white space.  Note: White Space.

`-l'
`--left-column'
     Print only the left column of two common lines.  Note: Side by
     Side Format.

`--minimal'
     Change the algorithm to perhaps find a smaller set of changes.
     This makes `sdiff' slower (sometimes much slower).  Note: diff
     Performance.

`-o FILE'
`--output=FILE'
     Put merged output into FILE.  This option is required for merging.

`-s'
`--suppress-common-lines'
     Do not print common lines.  Note: Side by Side Format.

`--speed-large-files'
     Use heuristics to speed handling of large files that have numerous
     scattered small changes.  Note: diff Performance.

`-t'
     Expand tabs to spaces in the output, to preserve the alignment of
     tabs in the input files.  Note: Tabs.

`--text'
     Treat all files as text and compare them line-by-line, even if they
     do not appear to be text.  Note: Binary.

`-v'
`--version'
     Output the version number of `sdiff'.

`-w COLUMNS'
`--width=COLUMNS'
     Use an output width of COLUMNS.  Note: Side by Side Format.
     Note that for historical reasons, this option is `-W' in `diff',
     `-w' in `sdiff'.

`-W'
     Ignore horizontal white space when comparing lines.  Note: White
     Space.  Note that for historical reasons, this option is `-w' in
     `diff', `-W' in `sdiff'.
