9.1 Specifying diff Options to sdiff

The following sdiff options have the same meaning as for diff. See section 13.1 Options to diff, for the use of these options.

-a -b -d -i -t -v -B -E -I regexp --ignore-blank-lines --ignore-case --ignore-matching-lines=regexp --ignore-space-change --ignore-tab-expansion --left-column --minimal --speed-large-files --strip-trailing-cr --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 section 2.4 Showing Differences Side by Side).
