Question with git push

["Paul Vincent Craven" <paul@cravenfamily.com>]

If I do a 'git push' to another repository, my changes are reverted
the next time that repository is updated, unless I do a hard reset on
the remote repository first. Of course, then I would lose my changes
in the remote repository. What is the correct way of handling this?

A quick example:

mkdir -p RepositoryA/files RepositoryB
cd RepositoryA/files
echo "Test file" > test1.txt
git init
git add .
git commit -a -m "Test Commit 1"
cd ../../RepositoryB
git clone ../RepositoryA/files
cd files
# I want this change to go to RepositoryA
echo "More data" >> test1.txt
git add .
git commit -a -m "Test Commit 2"
git push ../../RepositoryA/files
cd ../../RepositoryA/files
echo "Test file" > test2.txt
git add .
# This commit reverts test1.txt to not have "More data"
git commit -a -m "Test Commit 3" # This reverts test1.txt to not
git diff master^ master

How do I change my commands so I keep the change I made in RepositoryB?

Thanks,
