Unfortunately I have not found anything about wildcards in ”man eos cp”.

Question resolved or not? Wildcards and command features are described in the documentation:

man eos cp

Yes, I have tried this command. As a result, I have new /eos/nica/bmn/users/vplotnik/vp_r7_v2/ directory with vp_r7_v2 subdirectory. So after that, I need to execute 3 additional commands: rename /eos/nica/bmn/users/vplotnik/vp_r7_v2, move vp_r7_v2 to ../ and remove empty directory. It is not convenient.

But to be honest, wildcards is very helpful in many other situations. For example, to filter subdirectories which I want to copy. So my question was mainly about using wildcards with eos cp.

Have you tried like this?

eos cp -r -p -P /nica/mpd21/plotnikov/vp_r7_v2/ /eos/nica/bmn/users/vplotnik/vp_r7_v2/

I am trying to make a copy
eos cp -r -p -P /nica/mpd21/plotnikov/* /eos/nica/bmn/users/vplotnik/

I am trying to execute a command with no success
eos cp -r -p -P /nica/mpd21/plotnikov/vp_r7_v2/ /eos/nica/bmn/users/vplotnik/
error: unable to create directory (errc=1) (Operation not permitted)
error: failed to create target directory : /eos/nica/bmn/users/vplotnik/
Could you explain me why it so?

Describe in more detail what you want to do?
