How to sync changes in GIT to ClearCase or How to get the list of files changed in GIT for a specific branch

Hi Everyone, 

Thanks for looking into this thread.

This is a help on GIT to ClearCase sync and am using UNIX session and not Windows

I am intending to use ClearCase in the background and GIT in the front. For syncing files from ClearCase to GIT i checkout the git branch use rsync command to get the changed files in ClearCase and then i do the 'git add' and 'git commit'

This works out well, but i want to get a list of files changed in GIt so that i can bring that to ClearCase and checkout and checkin files.

Can someone provide me the commands to

1. Get list of files changed in GIT, after i do commit?
2. Get list of files changed in GIT after commit, but files changed after a
tag (baseline).
3. Sync these files to ClearCase?

Hope you gurus can help me....am in desperate need of these commands. Appreciate your help in this.

Thanks ask4thunder
