How to copy file to /usr/share on mac?

Question

I try to copy some file to /usr/share folder, but the terminal said that operation not permitted even I do the with sudo.
sudo cp ~/Downloads/kellys.vim /usr/share/vim/vim73/colors/
the result
cp: /usr/share/vim/vim73/colors/kellys.vim: Operation not permitted
When I try to change the permission of this folder, it came with the same problem. I run EI Capitan on Mac. I have google it for a long time,but still confused. How do I solve the problem ?

Solution 1

It looks like the problem you are having is more related to installing Vim colorschemes.

Those can be installed in ~/.vim/colors/.

mkdir -p ~/.vim/colors
cp ~/Downloads/kellys.vim ~/.vim/colors/

And then set it with

:colorscheme kellys

Update
If you really want your file in /usr, then the permissions on that folder are on lockdown and you can't edit it without disabling System Integrity Protection (SIP).

A folder that you can modify, however, is /usr/local/share.

So you can instead do

cp ~/Downloads/kellys.vim /usr/local/share/vim/vim73/colors/

Solution 2

U need to disable System Integrity Protection.

1. restarting and use Command ⌘-R on boot
2. open a terminal and execute command: csrutil disable
3. restart normally
4. NOW u can write in /usr dir tree
5. (optional) restart again, use Command ⌘-R on boot and execute again csrutil enable

Paste exact command that you run and exact output/errors you've got, it'll be easier to understand what you're trying to do.

Being you're running El Capitan, it's probably SIP's fault. You can disable SIP, but a better solution is the one in cricket_007's answer below.

Not sure why it downvoted but this is exactly what I was looking for. I actually needed to add something to /usr/bin not particularly just /usr So, you are back to whole. Thanks.
