How can I set file size restriction so that can't commit large file into repository ?

[kukadiya mayur]

Hello there,
I have one repository which I have shared with my colleagues. by mistake one of them push the large file into a repository and then the repository is fulled. So as a solution, I raise one ticket for ran garbage collector to reduce Repo size and they ran that. now my Repo size is under the size limit (2 GB)

I want to put restrictions on committing large files larger than 5mb. I try to find out a solution for this and I found a hook, But I don't know how to use that hook in Bitbucket to prevent large file commits. I am using git software with Bitbucket.

If anyone has an answer then please post here. The answer will be appreciated.
