I suppose you mean that the file manager processes the files that don't require user input and leaves the remaining files for further processing? In Krusader, you can set "confirm overwrites". I'm not sure what you mean by "re-enqueueing". Personally, I prefer the "Synchronize Directories" tool within Krusader because it lets me view a side-by-side list of non-identical files before I commit to overwriting anything: If you don't like the command line, you can use Grsync Īre you familiar with rsync? It "is a file synchronization and file transfer program for Unix-like systems that minimizes network data transfer by using a form of delta encoding." (from ). GNOME Commander is somehow programmable and therefore as smart as I tell it to be - I'd rather take advantage of more than just me ). I'm using Nautilus which does most of the opposite of these proposals, yet there's no smarter handling of directory merging in Dolphin, Thunar. support of ext4, Btrfs, CIFS (just to mention it, file access should be abstracted by the underlying kernel).immediate start of actions (not like Nautilus which counts the files and directories to transfer before starting).Together with the following features independent from directory merging:

optional: limited smart look-ahead in tree traversal: If the next files to be read are a 100 GB binary file and 15 small text files which require manual merging, it'd be smart to invoke the command for the first text files one after the other and compare the binary file in background when no I/O performance is required.warning dialog with information about missing permissions for files) (I don't want to order the transfer of 5 TB of data and then see the next morning that the transfer was interrupted after 100 MB asking what to do with this 5 KB file lacking permissions) re-enqueueing of files which need user input (e.g.allow invokation of external command for differing files with files passed as argument (e.g.compare files byte block by byte block if name and size is identical and overwrite if necessary without annoying non-sense question if files are identical.
Particularly, when we write a shell script, it can bring side effects.For a graphical Linux distribution I'm looking for a file navigator/browser which makes merging of two directory trees as smart and efficient as possible. Therefore, after the command execution, when we check the dotglob option, it is still disabled.Ĭhanging Bash’s default behavior works. Also, we wrap the shopt command together with the cp command in “ (….)” to make them run in a subshell since we want the shopt command only to affect the single cp command. We can use the shopt -s dotglob command to achieve that: $ ( shopt -s dotglob cp -r src/* target )Īs we can see in the output above, the dotfile has also been copied. One way is to change the default setting and make the globbing include dotfiles. This is because the default globbing in Bash does not include filenames starting with a dot (“.”). First, let’s clean the target directory and give it a try, and see what will happen: $ cp -r src/* targetĪs the tree output shows, almost everything under src has been copied to the target directory, except for the dotfile. However, there is a little flaw in the command. Indeed, this is another possibility to solve the problem. Therefore, we may come up with the command cp -r src/* target. If we reconsider the problem, the requirement is only to copy the content under src. We’ve solved the problem using the cp command with -rT options.

Next, we’ll address how to achieve our objective using two different approaches: That is because this command will copy the whole src directory under target as a subdirectory: /target/src/. Since the target directory exists already, we cannot simply use the command cp -r src target to do this job. Also, the original files under target must be untouched. However, if we copy without overwriting, we want everything under the src directory to be recursively copied to the target directory. If we copy with overwriting, after the copy operation, we want the target directory to contain exactly the same content as the src directory. Now, we want to copy the src directory to the target directory.
