So easy~

Copy Directory

format: cp-r source directory target directory (and rmdir , you need to add   -r   option)

a convention: When the CP directory, the final     all to be entered. Avoid late-stage problems

Some points of note for the CP command

which cp

CP command is aliased, with a RM the command, ask if you want to delete a file.

chestnuts:

1. txt files already exist under the current/tmp/directory, if we do it again   , then this option will work.

If you do not want this query, you can use the absolute path of the CP directly to operate

For the copy file, whenever the file already exists, will ask, then for the copy directory, is the case the same?

Chestnuts:

cp-r/tmp/allin//tmp/allin1/, verify the problem.

So let's see what happens to the structure of the current two directories.

explanation CP Command, when replicating directories, if the target directory (/allin1/) already exists, it does not overwrite the target directory, but instead puts the source directory (/allin/), copied intact to the existing target directory (/allin1/). When you perform such an operation again, the query does not appear to overwrite.
