Git - how to find out if there have been changes in certain files?

Question

git

The task is this: to find out whether there have been changes in certain files and directories of the current branch since its creation. The command will be executed by a bash script.
There is, for example, such a command:
git diff --name-only master -- dirname
It gives practically what is needed, but the changes made to the branch with which it is being compared are also taken into account. And you need to find out if there have been changes in the current one.

Answer 1

git diff --name-only $(git merge-base <текущая ветка> master) -- dirname
