Detailed Description of Context Format
......................................
The context 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 normally looks like `2002-02-21 23:30:39.942229878
-0800' to indicate the date, time with fractional seconds, and time
zone in Internet RFC 2822 format
(ftp://ftp.isi.edu/in-notes/rfc2822.txt). However, a traditional time
stamp like `Thu Feb 21 23:30:39 2002' is used if the `LC_TIME' locale
category is either `C' or `POSIX'.
You can change the header's content with the `--label=LABEL' option;
see Alternate Names.
Next come one or more hunks of differences; each hunk shows one area
where the files differ. Context format hunks look like this:
***************
*** FROM-FILE-LINE-RANGE ****
FROM-FILE-LINE
FROM-FILE-LINE...
--- TO-FILE-LINE-RANGE ----
TO-FILE-LINE
TO-FILE-LINE...
The lines of context around the lines that differ start with two
space characters. The lines that differ between the two files start
with one of the following indicator characters, followed by a space
character:
`!'
A line that is part of a group of one or more lines that changed
between the two files. There is a corresponding group of lines
marked with `!' in the part of this hunk for the other file.
`+'
An "inserted" line in the second file that corresponds to nothing
in the first file.
`-'
A "deleted" line in the first file that corresponds to nothing in
the second file.
If all of the changes in a hunk are insertions, the lines of
FROM-FILE are omitted. If all of the changes are deletions, the lines
of TO-FILE are omitted.
