The patch utility is the tool here. Try 'man patch' for fuller
instructions, but basically you just type
$ patch -pN < PATCHFILE
where N is a number representing the number of subdirectory levels which
need to be stripped from the pathnames given in the patchfile in order
for the utility to be able to find the files it needs to patch, relative
to your current working directory, and PATCHFILE is the name of the file
containing the patches. For example, if you look at the patches I most
recently posted, you'll see the following two lines near the top:
--- original/ParameterUtils.java Mon Jul 17 00:41:05 2000
+++ modified/ParameterUtils.java Wed Aug 2 12:06:36 2000
So you would navigate to the directory which has the ParameterUtils.java
file in it (probably ..../freetds_jdbc) and issue the command:
$ patch -p1 < ParameterUtils.diff
... assuming that's what you named the diff output I posted. The option
-p1 reflects the fact that you want patch to strip off the "original/"
and "modified/" pathname prefixes, which has one (1) unwanted level of
depth to the path. If it said "bob/src/original/ParameterUtils.java"
and "bob/src/modified/ParameterUtils.java" you would instead use -p3
because there are three superfluous levels to be stripped (count the
slashes). On the other hand, if you have "original/unittests/Makefile"
then you only want to use "-p1" because you need to preserve the
"unittests/" portion (and you need to be positioned in the parent
directory of unittests).
Make any sense?
