16.1 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'
'--text'
     Treat all files as text and compare them line-by-line, even if they
     do not appear to be text.  Note: Binary.

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

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

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

'--diff-program=PROGRAM'
     Use the compatible comparison program PROGRAM to compare files
     instead of 'diff'.

'-E'
'--ignore-tab-expansion'
     Ignore changes due to tab expansion.  Note: White Space.

'--help'
     Output a summary of usage and then exit.

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

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

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

'-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.

'--strip-trailing-cr'
     Strip any trailing carriage return at the end of an input line.
     Note: Binary.

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

'--tabsize=COLUMNS'
     Assume that tab stops are set every COLUMNS (default 8) print
     columns.  Note: Tabs.

'-v'
'--version'
     Output version information and then exit.

'-w COLUMNS'
'--width=COLUMNS'
     Output at most COLUMNS (default 130) print columns per line.  Note:
     Side by Side Format.  Note that for historical reasons, this
     option is '-W' in 'diff', '-w' in 'sdiff'.

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

'-Z'
'--ignore-trailing-space'
     Ignore white space at line end.  Note: White Space.
