9.1 Specifying diff Options to sdiff

The following sdiff options have the same meaning as for diff. See Options to diff, for the use of these options.

-a -b -d -i -t -v
-B -E -I regexp -Z

--ignore-blank-lines  --ignore-case
--ignore-matching-lines=regexp  --ignore-space-change
--ignore-tab-expansion  --ignore-trailing-space
--left-column  --minimal  --speed-large-files
--strip-trailing-cr  --suppress-common-lines
--tabsize=columns  --text  --version  --width=columns

For historical reasons, sdiff has alternate names for some options. The -l option is equivalent to the --left-column option, and similarly -s is equivalent to --suppress-common-lines. The meaning of the sdiff -w and -W options is interchanged from that of diff: with sdiff, -w columns is equivalent to --width=columns, and -W is equivalent to --ignore-all-space. sdiff without the -o option is equivalent to diff with the --side-by-side (-y) option (see Showing Differences Side by Side).
