Hi Assaf!
Thank you for your quick response!
There is always multiple ways to do things. The git tool has a diff tool built
in that makes file comparison easy.
I have run across multiple times that copying one tree over another is
desirable.
In another bug message thread, we found that the cause was cp alias to 'cp -i'
for root user was the actual cause.
This still left the incorrect operation of the interactive operation when both
-i and -f is used.
I think that in some cases the need of override the '-i' with '-f' maybe very
desirable. So maybe having the '-f' cancel or override the '-i' operation might
be a good change.
Thanks!
Mike

This is slightly off-topic, but if you want to compare only files managed by
git (ignoring other files in current directory), perhaps the following would
help:
# Download and extract the tarball
wget -q http://dpdk.org/browse/dpdk/snapshot/dpdk-1.7.1.tar.gz
tar -xf dpdk-1.7.1.tar.gz
# Clone the git repo with specific branch, checkout the relevant branch
# (or go to an existing checked-out repository directory)
git clone git://dpdk.org/dpdk
cd dpdk
git checkout -b map_v1.7.1 v1.7.1
# For each file managed by git (with 'git ls'),
# compare it to the corresponding file in the other directory:
git ls -0 | xargs -0 -I% diff -q % ../dpdk-1.7.1/%
