sdiff - side-by-side difference program
sdiff [ options ... ] file1 file2
sdiff uses the output of diff(1) to produce a side-by-side listing of two
files indicating those lines that are different. Each line of the two
files is printed with a blank gutter between them if the lines are
identical, a < in the gutter if the line only exists in file1, a > in the
gutter if the line only exists in file2, and a | for lines that are
different.
For example:
x | y
a a
b <
c <
d d
> c
The following options exist:
-w n Use the next argument, n, as the width of the output line.
The default line length is 130 characters.
-l Only print the left side of any lines that are identical.
-s Do not print identical lines.
-o output Use the next argument, output, as the name of a third file
that is created as a user-controlled merging of file1 and
file2. Identical lines of file1 and file2 are copied to
output. Sets of differences, as produced by diff(1), are
printed; where a set of differences share a common gutter
character. After printing each set of differences, sdiff
prompts the user with a % and waits for one of the following
user-typed commands:
l append the left column to the output file
r append the right column to the output file
s turn on silent mode; do not print identical lines
v turn off silent mode
e l call the editor with the left column

e r call the editor with the right column
e b call the editor with the concatenation of left
and right
e call the editor with a zero length file
q exit from the program
On exit from the editor, the resulting file is concatenated on
the end of the output file.
