Invoking sdiff
The sdiff command merges two files and interactively outputs the results.
Its arguments are:
sdiff -o outfile options ...from-file to-file.
This merges
from-file with to-file, with output to outfile.If from-file is a directory and to-file is not, sdiff compares the file in from-filewhose file name is that of to-file, and vice versa. from-file and to-file may not both be directories.
sdiff options begin with '-', so normally from-file and to-file may not begin with '-'. However, '--' as an argument by itself treats the remaining arguments as file names even
if they begin with '-'. You may not use '-' as an input file. An exit status of 0 means no differences were found, 1
means some differences were found, and 2 means trouble.
sdiff without '-o' (or '--output') produces a side-by-side difference. This usage is obsolete; use 'diff --side-by-side' instead.

Options to sdiff.
