NAME
sdiff - side-by-side difference program
SYNOPSIS
sdiff [ -w n ] [ -l ] [ -s ] [ -o output ] filename1
filename2
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 filename1, a > in the
gutter if the line only exists in filename2, and a | (pipe)
for lines that are different. (See EXAMPLES Section.)
OPTIONS
-l Only print the left side of any lines that are
identical.
-o output
Use the next argument, output, as the name of a third
file that is created as a user-controlled merging of
filename1 and filename2. Identical lines of filename1
and filename2 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

q Exit from the program
On exit from the editor, the resulting file is
concatenated on the end of the output file.
The editor used will be determined by the value
contained in the environment variable EDIT. If
it has not been set, ed is used by default.
-s Do not print identical lines.
-w n
Use the next argument, n, as the width of the output
line. The default line length is 130 characters.
EXAMPLES
Given the file foo.1 composed of the letters x, a, b, c, and
d on individual lines, and the file foo.2 similiarly
composed of the letters y, a, d, and c, the following
results will ocurr:
sdiff foo.1 foo.2
x | y
a a
b <
c <
d d
> c
VARIABLES
EDIT The editor to be used with the -o option.
RETURN VALUE
[NO_ERRS] Command completed without error.
[USAGE] Incorrect command line syntax. Execution
terminated.
[NP_WARN] An error warranting a warning message
occurred. Execution continues.
[P_ERR] A system error occurred. Execution
terminated. See intro(2) for more
information on system errors.
CAVEATS
Sdiff executes diff(1) in order to process the input files.
If a line coming from diff is longer than 200 characters, an
error message is printed and sdiff exits.
