#Rust installation instructions go like:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

But what you actually want to do most of the time, is probably:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | bash -s -- --no-modify-path

#rustlang

@jarkko This is my first time seeing --no-modify-path. Thanks!

@jon_giraffe for more options:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | bash -s -- --help

@jon_giraffe or if you want to go crazy:

$ alias rustup-init="curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s --"
$ rustup-init --help

Execution of a remote payload but should be fairly secure as it is verified with rust-lang.org CA (thanks to TLS 1.2).
