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.)
-lPrint only the left side of any lines that are identical.to
-sDo not print identical lines.
-o outputUse 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:
lAppend the left column to the output file.
rAppend the right column to the output file.
sTurn on silent mode; do not print identical lines.
vTurn off silent mode.
e lCall the editor with the left column.
e rCall the editor with the right column.
e bCall the editor with the concatenation of left and right.
eCall the editor with a zero length file.
qExit from the program.
On exit from the editor, the resulting file is concatenated to the end of the output file.
-w nUse 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).
Example 1 An example of the sdiff command.
A sample output of sdiff follows.
x | y a a b < c < d d > c
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" locale determines how sdiff behaves.
LC_CTYPEDetermines 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.
