sdiff - print differences between two files side-by-side
sdiff [-l] [-s] [-o output] [-w n] filename1 filename2
sdiff uses the output of the diff command to produce a
side-by-side listing of two files indicating lines that are
different. Lines of the two files are printed with a blank
gutter between them if the lines are identical, a < in the
gutter if the line appears only in filename1, a > in the
gutter if the line appears only in filename2, and a | for
lines that are different. (See the EXAMPLES section below.)
-l Print only the left side of any lines that are
-s Do not print identical lines.
Use the argument output as the name of a third file
that is created as a user-controlled merge of
filename1 and filename2. Identical lines of filename1
and filename2 are copied to output. Sets of differ-
ences, as produced by diff, 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
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
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
e Call the editor with a zero length file.
q Exit from the program.
On exit from the editor, the resulting file is con-
catenated to the end of the output file.
-w n Use the argument n as the width of the output line.
The default line length is 130 characters.
See largefile(5) for the description of the behavior of
sdiff when encountering files greater than or equal to 2
Gbyte ( 2**31 bytes).

If any of the LC_* variables ( LC_CTYPE, LC_MESSAGES,
LC_TIME, LC_COLLATE, LC_NUMERIC,
and LC_MONETARY ) (see environ(5)) are not set in the
environment, the operational behavior of sdiff for each
corresponding locale category is determined by the value of
the LANG environment variable. If LC_ALL is set, its con-
tents are used to override both the LANG and the other LC_*
variables. If none of the above variables is set in the
environment, the "C" locale determines how sdiff behaves.
Determines how sdiff handles characters. When LC_CTYPE
is set to a valid value, sdiff can display and handle
text and filenames containing valid characters for
