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).
