sdiff(C)


sdiff -- compare files side-by-side

Syntax

sdiff [ options ... ] file1 file2

Description

The sdiff command uses the output of diff(C) 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:

   	x	|	y
   	a		a
   	b	<
   	c	<
   	d		d
   		>	c

The following options exist:


-w n
Uses the next argument, n, as the width of the output line. The default line length is 130 characters.

-l
Only prints the left side of any lines that are identical.

-s
Does not print identical lines.

-o output
Uses 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, 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-entered commands:

l
Appends the left column to the output file.

r
Appends the right column to the output file.

s
Turns on silent mode; does not print identical lines.

v
Turns off silent mode.

e l
Calls the editor with the left column.

e r
Calls the editor with the right column.

e b
Calls the editor with the concatenation of left and right.

e
Calls the editor with a zero length file.

q
Exits from the program.
On exit from the editor, the resulting file is concatenated on the end of the output file.
