sdiff(1) User Commands sdiff(1)NAMEsdiff - print differences between two files side-by-side
SYNOPSISsdiff [-l] [-s] [-o output] [-w n] filename1 filename2
DESCRIPTIONsdiff 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.)
OPTIONS-l Print only the left side of any lines that are identi‐
cal.to
-s Do not print identical lines.
-o output 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 file‐
name2 are copied to output. Sets of differences, as
produced by diff, are printed; where a set of differ‐
ences 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 com‐
mands:
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 concate‐
nated 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.
USAGE
See largefile(5) for the description of the behavior of sdiff when
encountering files greater than or equal to 2 Gbyte ( 2**31 bytes).

ENVIRONMENT VARIABLES
If any of the LC_* variables ( LC_CTYPE, LC_MESSAGES, LC_TIME, LC_COL‐
LATE, 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 contents 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.
LC_CTYPE 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 that
locale.
