patch files are generated from the diff command, so maybe a 'man diff'
could clarify a bit more for you.
the output of diff is basically a comparison between two files.
without -u option the output looks like this:
2,3c2,3
< # For a description of the syntax of this configuration file,
< # see Documentation/kbuild/kconfig-language.txt.
- ---
> # Per una descrizione della sintassi di questo file di
configurazione
> # vedere Documentation/kbuild/kconfig-language.txt.
first you will see in what rows the difference is (the numbers at the
top), then the difference between files is shown prepending '<' and
'>' before the lines, respectively for the lines in the first file and
the lines in the second.
if we give diff the -u option, then the output will be like this:
- --- 2.6.12-en/arch/alpha/Kconfig 2005-06-19 16:38:51.000000000
+0200
+++ 2.6.12-it/arch/alpha/Kconfig 2005-06-26 10:12:49.000000000
+0200
@@ -1,14 +1,15 @@
#
- -# For a description of the syntax of this configuration file,
- -# see Documentation/kbuild/kconfig-language.txt.
+# Per una descrizione della sintassi di questo file di configurazione
+# vedere Documentation/kbuild/kconfig-language.txt.
this time we have the name of compared files, then the different rows
(between '@@'), and the prefix for different lines is now a plus or
minus sign.
this is the format of diff file to give as input for patch; patch will
remove lines starting with '-' and add lines starting with '+' (unless
you specify the -R option :)
