Get changes from a remote repository?

Question

git

Good day to all! I need to synchronize the code on the remote repository and on my local one. a lot of changes have accumulated on the remote and I need to have the same thing on my local. I do:
git pull origin dev
Nothing really changes. Tell me what's wrong??!?
PS The Update button in PHPStorm is the same git pull?!??

Answer 1

As a result, I solved the problem with the following series of commands:

git checkout -- .
git clean -fd
git reset --hard origin/dev

Answer 2

Maybe you should do git fetch first
and then git pull
