Why won't my cp command copy whole directories? [duplicate]

I've tested the cp command, and it will only copy individual files. For example, I typed cp followed by the exact filename, then typed the directory and the file got copied. However, when I typed the directory and the destination directory, nothing on the computer changed. I thought cp was supposed to copy contents in the directories.

I've tried this multiple times.

Solution 1:

When you use cp without any arguments, it defaults to copying files as below

 cp sourcefile destinationLocation
 #will copy sourcefile to the specified destinationLocation

But if you want to copy a directory, you need to specify the recursive argument like this

cp -R dir1 dir2 #copies dir1 to dir2
cp -R dir dir2 dir3 #copies dir1 & dir2 to dir3

Ideally you can specify as many files as you want to a single destination all separated by spaces. This here below however copies a dir along with its permissions

 sudo cp -rp /home/me /media/backup/me
 -p     same as --preserve=mode,ownership,timestamps

Alternatively you can use rsync

 sudo rsync -a /home/me/ /media/backup/me/
 -a, --archive

          Note that -a does not preserve hardlinks, because finding  multiply-linked
          files is expensive.  You must separately specify -H.

And Please don't forget the trailing slashes when copying using rsync. See the man page for each command on options of using them available on your terminal by typing man cp or man rsync

Solution 2:

Use

cp -R

It specifies recursive copy i.e. all sub-directories and files will be copied. Use man cp to find more switches for cp.
