Detailed Description of Unified Format
The unified output format starts with a two-line header, which looks
like this:
--- from-file from-file-modification-time
+++ to-file to-file-modification-time
The time stamp looks like 2002-02-21 23:30:39.942229878 -0800
to indicate the date, time with fractional seconds, and time zone.
You can change the header's content with the
--label=label option; see See Alternate Names.
Next come one or more hunks of differences; each hunk shows one area
where the files differ. Unified format hunks look like this:
@@ from-file-range to-file-range @@
line-from-either-file
line-from-either-file...
The lines common to both files begin with a space character. The lines
that actually differ between the two files have one of the following
indicator characters in the left print column:
+
- A line was added here to the first file.
-
- A line was removed here from the first file.
