]
filename1
filename2

for information on how to install optional software.
DESCRIPTION
sdiff
uses the output of
diff-b
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
filename1,
a
>
in the gutter
if the line only exists in
filename2,
and a
|
for lines that are different.
See
EXAMPLES.
OPTIONS
- -w n
-
Use
n
as the width of the output line.
The default line length is 130 characters.
- -l
-
Only print the left side of any identical lines.
- -s
-
Silent. Do not print identical lines.
- -o outfile
-
Use the next argument,
output,
as the name of an output file created as
an interactively controlled merging of
filename1
and
filename2.
Identical lines of
filename1
and
filename2
are copied to
output.
Sets of differences, as produced by
diff,
are printed; where a set of differences share a
common gutter character.
After printing each set of differences,
sdiff
prompts with a
%
and waits for you to type one of the following 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
ed.1
with the left column.
- e r
-
Call
ed.1
with the right column.
- e b
-
Call
ed.1
with the concatenation of left and right columns.
- e
-
Call
ed.1
with a zero length file.
On exit from
ed.1
the resulting file is concatenated to the named output file.
- q
-
Exit from the program.
EXAMPLES
A sample output of
sdiff
would look like this:
-
x | y
a a
b <
