Can Gitlab run a bash script on the server?

Question

linux

In general, the task is simple and understandable. It is necessary that when pushing to the master branch, one bash script is launched on the server, and when pushing to the qa branch, another.
Can this be done using gitlab? (!Important - not a webhook).
If so, how? Describe what to do. If not, how can this be done?
