NAME

sdiff − print file differences side-by-side

SYNOPSIS

sdiff [ options ] file1 file2

DESCRIPTION

sdiff uses the output of diff(1) 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 file1, a > in the gutter if the line appears only in file2, and a | for lines that are different.  For example:

x|y
aa
b<
c<
dd
>c

Valid options are:

−w  n Use the argument n as the width of the output line.  The default line length is 130 characters. 

−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 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-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.
