Are these commands materially, or only semantically different?
Clash Royale CLAN TAG#URR8PPP
In a shell script that's using curl to fetch a script, then executing it, are these two approaches materially different?
curl http://address-to-some-script/dosomething.sh | sudo tee /usr/bin/dosomething.sh
...vs...
sudo curl http://address-to-some-script/dosomething.sh >> /usr/bin/dosomething.sh
There's something about the sudo right before curl in the second command that's giving me pause, but I can't articulate whether or how it's different (riskier?) than the first.

There are a number of material differences.
curl http://address-to-some-script/dosomething.sh | sudo tee /usr/bin/dosomething.sh
runs curl as the current user, and tee as root; it also clears the contents of /usr/bin/dosomething.sh before writing to it.
sudo curl http://address-to-some-script/dosomething.sh >> /usr/bin/dosomething.sh
runs curl as root, and tries to append to /usr/bin/dosomething.sh with the permissions of the current user (the current shell sets the redirection up).
