Node:Detailed Normal, Next:, Up:Normal

Detailed Description of Normal Format

The normal output format consists of one or more hunks of differences; each hunk shows one area where the files differ. Normal format hunks look like this:

change-command
< from-file-line
< from-file-line...
---
> to-file-line
> to-file-line...

There are three types of change commands. Each consists of a line number or comma-separated range of lines in the first file, a single character indicating the kind of change to make, and a line number or comma-separated range of lines in the second file. All line numbers are the original line numbers in each file. The types of change commands are:

lar
Add the lines in range r of the second file after line l of the first file. For example, 8a12,15 means append lines 12-15 of file 2 after line 8 of file 1; or, if changing file 2 into file 1, delete lines 12-15 of file 2.
fct
Replace the lines in range f of the first file with lines in range t of the second file. This is like a combined add and delete, but more compact. For example, 5,7c8,10 means change lines 5-7 of file 1 to read as lines 8-10 of file 2; or, if changing file 2 into file 1, change lines 8-10 of file 2 to read as lines 5-7 of file 1.
rdl
Delete the lines in range r from the first file; line l is where they would have appeared in the second file had they not been deleted. For example, 5,7d3 means delete lines 5-7 of file 1; or, if changing file 2 into file 1, append lines 5-7 of file 1 after line 3 of file 2.
