Oh ok

[starzation]

@apprehensions Do you want me to close this pr or merge this while i move this to upstream lib?

[apprehensions]

Discuss with library maintainer to determine if this patch belongs there or here.

@apprehensions Found out it wasn't upstream lib issue we need to check if file already exists first. (otiai10/copy#132)

[apprehensions]

Sorry for getting to this PR late, but does the solution have to be this complicated?

[apprehensions]

If possible, it would be greatly appreciate to test this, just to enforce and proof the new behavior. A guide on how to make Go tests can be found here.

I have added test cases, I am not sure if this is what you want.

Please fix conflicts for merge. Thanks for your work as well.

Do try to use slog as well for logging.

@apprehensions Maybe you can close this now since otiai10/copy#145 has been merged.

[apprehensions]

I have asked the pull request and the issue author to verify if the issue has been solved. If it is for you having faced this issue, please let me know.
To do that a Go module upgrade will be required.

[apprehensions]

I have checked myself and the PR fixes it.

Thank you for your work @starzation
