NAME [Toc] [Back]
sdiff - side-by-side difference program
SYNOPSIS [Toc] [Back]
sdiff [options ...] file1 file2
DESCRIPTION [Toc] [Back]
sdiff uses the output of diff(1) with the -b option, which ignores
trailing blanks (spaces and tabs) and treats other strings of blanks
as equal, 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 file1, a > in the gutter if the
line only exists in file2, and a | for lines that are different.
For example:
abc | xyz
abc abc
bca <
cba <
dcb dcb
> cde
Options [Toc] [Back]
sdiff recognizes the following options:
-w n Use the next argument, n, as the width of the output
line. The maximum value of n is 2048 (LINE_MAX). The
default line length is 130 characters.
-l Only print on the left side when lines are identical.
-s Do not print identical lines.
-o output Use the next argument, output, as the name of a third
file that is created as a user-controlled merging of
file1 and file2. Identical lines of file1 and file2
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 file
q exit from the program
On exit from the editor, the resulting file is
concatenated on the end of the output file.
EXAMPLES [Toc] [Back]
Print a side-by-side diff of two versions of a file on a printer
capable of printing 132 columns:
sdiff -w132 prog.c.old prog.c | lp -dlineprinter
Retrieve the most recently checked in version of a file from RCS and
compare it with the version currently checked out:
co -p prog.c > /tmp/$$; sdiff /tmp/$$ prog.c | more; rm /tmp/$$
