patch command

[Samit Gupta]

I have a couple of questions about the patch command. How is
running patch any different from just copying the versions of
files from the project 2 solution over those same files in the
project 3 directory? I'm also confused as per what the command
syntax for patch should be for our purposes. Thanks.

I've changed the instructiuons on the webpage. See the
'Incorporating your project 2 sources' section in
http://www.cs.umd.edu/class/spring2005/cmsc412/proj3/

the commands on the website didn't work. i managed to get them working with this:

$ cd ~/project2/src/geekos
$ diff -u -r . ~/project3/src/geekos > ~/diff.patch
$ cd ~/project3/src/geekos
$ patch -p0 < ~/diff.patch
$ rm *orig

NOTE: i don't have the P2-solution "yet" so i had to use my implementation.
