Specifying diff Options to sdiff

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

-a -b -d -i -t -v
-B -H -I regexp
--ignore-blank-lines --ignore-case
--ignore-matching-lines= regexp --ignore-space-change
--left-column --minimal --speed-large-files
--suppress-common-lines --expand-tabs
--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 '-y' or '--side-by-side' option (see Showing Differences Side by Side).
