阅读更多关于 last_write_time Mismatch on Copied Directories

问题 I'm uncertain whether this is a platform difference or an implementation difference. I'm hoping that someone can help me shed light on that. Given this code: filesystem::path foo("foo"); filesystem::path bar("bar"); filesystem::create_directories(foo); filesystem::copy(foo, bar); const auto fooftime = filesystem::last_write_time(foo); const auto barftime = filesystem::last_write_time(bar); const auto foocftime = decltype(fooftime)::clock::to_time_t(fooftime); const auto barcftime = decltype

Preorder tree traversal copy folder

阅读更多关于 Preorder tree traversal copy folder

问题 We have a database that contains several Trees. These trees are build using the "Preorder tree traversal" principle. This is a very powerful way of creating trees but it has one big disadvantage, adding multiple nodes at once. We have to create a copy function in our tree, copying a single (lowest level) node is very easy, you can do this in one call. But now we want to copy a whole folder at once. We were wondering if we should do this in .net of with a stored procedure. We have to make sure

How can I rename a directory in bash, without overwriting or moving inside a pre-existing target?

阅读更多关于 How can I rename a directory in bash, without overwriting or moving inside a pre-existing target?

问题 I want to rename a directory, only if the target does not exist. To do this the syntax should be mv -n -T my/dir my/dirNew Where -n means "don't overwrite" and -T means "don't move into the target" (https://askubuntu.com/a/763915/461996) Unfortunately, -T is not an option on OSX, so any scripts making use of it won't work for OSX. So, how can I rename a directory only if it won't overwrite one? I've checked, and rename is not a standard I can depend on. 回答1: If its not necessary for you to
