SDIFF(1) (Directory and File Management Utilities) SDIFF(1)
NAME
sdiff - side-by-side difference program
SYNOPSIS
sdiff [ options ... ] file1 file2
DESCRIPTION
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.
