Why can't I create links in /bin?
I am using MacOs Mojave, and I figured that the env binary sits under /usr/bin/env. Now we have a bunch of shell scripts (written and working under linux) that have /bin/env hardcoded for the shebang line.
I thought a simple:
cd /bin
sudo ln -s /usr/bin/env env
or maybe
sudo cp /usr/bin/env .
should do the trick, but I get:
ln: env: Operation not permitted
(same for cp).
Any idea how to fix this?

The lesson here is that shebangs aren't supposed to be portable between machines; they are a convenience for use on one machine.

While you could go ahead and disable System Integrity Protection, I do not recommend it.
Instead, change your shebangs to use /usr/bin/env; that's where env belongs.
Apparently some Linux distros contain env both in /bin and in /usr/bin, but some (including Debian and probably derivatives) don't. Neither does macOS, and I bet other BSDs don't, either.
