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.
Treat all files as text and compare them line-by-line, even if they do not appear to be text. See Binary.
Ignore changes in amount of white space. See White Space.
Ignore changes that just insert or delete blank lines. See Blank Lines.
Change the algorithm to perhaps find a smaller set of changes. This
sdiff slower (sometimes much slower). See diff Performance.
Use the compatible comparison program program to compare files
Ignore changes due to tab expansion. See White Space.
Output a summary of usage and then exit.
Ignore changes in case; consider upper- and lower-case to be the same. See Case Folding.
Ignore changes that just insert or delete lines that match regexp. See Specified Lines.
Print only the left column of two common lines. See Side by Side Format.
Put merged output into file. This option is required for merging.
Do not print common lines. See Side by Side Format.
Use heuristics to speed handling of large files that have numerous scattered small changes. See diff Performance.
Strip any trailing carriage return at the end of an input line. See Binary.
Expand tabs to spaces in the output, to preserve the alignment of tabs in the input files. See Tabs.
Assume that tab stops are set every columns (default 8) print columns. See Tabs.
Output version information and then exit.
Output at most columns (default 130) print columns per line.
See Side by Side Format. Note that for historical reasons, this
option is -W in

Ignore white space when comparing lines. See White Space.

Ignore white space at line end. See White Space.
