How to pull one file in git?

Question

git

I must be specifying the path to the file incorrectly

git checkout 6g25701874aa5a2c16cc6275fa30baa5b6e477a8 block/prod/work/class/MyFile.php

Error:
fatal: reference is not a tree: 6g25701874aa5a2c16cc6275fa30baa5b6e477a8
Googled, usually such an error occurs when updating. What is the reason? I want to pull from the master, but now I'm in another branch, is it necessary to change the branch before pulling? Or am I incorrectly specifying the path to the file, is it necessary with the name of the project in its entirety or in some other way?

Answer 1

If you just need to checkout a file from the master, then just take the file from the master:
git checkout master -- block/prod/work/class/MyFile.php
