sdiff - print differences between two files side-by-side
sdiff
[ -l ] [ -s ] [ -o output ] [ -w n ] filename1 filename2
SUNWesu
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 identical.
- -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 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 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 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.
A sample output of sdiff follows.

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 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" (U.S. style) 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. sdiff can display and handle Extended Unix
Code (EUC) characters where any individual character can be 1, 2, or 3
bytes wide. sdiff can also handle EUC characters of 1, 2, or more column
widths. In the "C" locale, only characters from ISO 8859-1 are valid.
