Files copied with cp are disappearing or not arriving as expected

I'm trying to copy

~/Desktop/profiles/a.mobileprovision

to

~/Library/MobileDevice/Provisioning Profiles

. Whether or not that's a good idea is not the topic of this question. The files never appear, even when doing an

-la

. Here's my procedure. 1.

$ cd ~/Library/MobileDevice/Provisioning Profiles

// cd is working as expected. 2.

$ cp ~/Desktop/profiles/a.mobileprovision .

3.

$ find . -name "a.mobileprovision"

nothing. Permissions for the directory:

-xr-x

, so I should be allowed. I'm on a Mac (Monterey 12.5), so I've also tried: 1. Opening up

~/Library/MobileDevice/Provisioning Profiles

in Finder and dragging and dropping

.mobileprovision

, but it disappears upon releasing the mouse. I've got hidden files showing. No luck. 2. Copying

.mobileprovision

to

~/Library/MobileDevice

. This works fine, but when I try to copy it to

~/Library/MobileDevice/Provisioning Profiles

, it does not. **Responses to comments:** 3. Doing

$ pwd

after the cd yields

~/Library/MobileDevice/Provisioning Profiles

4. Doing

$ cp ~/Desktop/profiles/a.mobileprovision ~/Library/MobileDevice/Provisioning Profiles

has the same effect: no copy performed. 5. Mac version: Monterey 12.5 (switched to bash from zsh). 6.

$ cp -v ~/Desktop/profiles/a.mobileprovision .

yields

~/Desktop/profiles/a.mobileprovision -> ./a.mobileprovision

7.

. -name ""

while in

~/Library/MobileDevice/Provisioning Profiles

is working. 8. Tried

~/Desktop/profiles/a.mobileprovision ~/Library/MobileDevice/'Provisioning Profiles'

. Same problem. Thanks for the help!
