What is the meaning of the double dashes before the file name in this git command?
git checkout --ours -- path/to/file.txt
git checkout --theirs -- path/to/file.txt
Are they mandatory? Is it equivalent to
git checkout --ours path/to/file.txt
git checkout --theirs path/to/file.txt
回答1:
Suppose I have a file named path/to/file.txt in my Git repository, and I want to revert changes on it.
git checkout path/to/file.txt
Now suppose that the file is named master...
git checkout master
Whoops! That changed branches instead. The -- separates the tree you want to check out from the files you want to check out.
git checkout -- master
It also helps us if some freako added a file named -f to our repository:
git checkout -f # wrong
git checkout -- -f # right
This is documented in git-checkout: Argument Disambiguation.

The double dash "--" means "end of command line flags" i.e. it tells the preceding command not to try to parse what comes after command line options.
