sdiff [-ls] [-o name] [-w width] file1 file2

sdiff presents the lines of file1 and file2 side-by-side in two columns. Lines that are equal in both files are separated by blanks; lines that differ are separated by one of the following characters:

<	the line is in file1 only
|	the line differs in file1 and file2
>	the line is in file2 only.

This might look as

only in file1        < 
in both files           in both files
this line            |  is different
                     >  only in file2
also in both files      also in both files

The behavior of sdiff can be influenced with the following options:

-l	Print the first column only for lines equal in both files.
-s	Omit equal lines in output.
-w width	Set the width of output (both lines and separators added) to width; the default is 130. Long lines are truncated to fit within this space.
-o name	Generate a merged version of both input files in the file name in addition to normal output. Lines that are equal are written to name; for each set of different lines, the prompt '%' is printed and the user may then choose the action by typing one of the following commands: l Write the lines of the left (first) file to name. r Write the lines of the right (second) file to name. s Do not print equal lines to standard output. v Turn printing of equal lines on. e l Invoke the editor on the lines of the left file and append the result to name. e r Invoke the editor on the lines of the right file. e b Concatenate the lines of both files and invoke the editor on the result. e Invoke the editor with an empty file. q Quit sdiff and do not write further lines to name.
