I dont think there is a single command to do it for *all*
branches, but for any particular branch, this should work:

    git merge --ff-only @{u}

So what you want would boil down to this script (untested):

    #!/bin/bash
    git status --porcelain -uno | grep . && {echo dirty tree, exiting...; exit 1; }

    for b in `git for-each-ref '--format=%(refname:short)' refs/heads`
    do
        git checkout $b
        git merge --ff-only @{u}
    done
