How can I pass parameter into bash while scripts it executes are piped in

Question

What I meant is when I am executing bash scripts using this kind of formart:

bash < <( curl http://rvm.io/releases/rvm-install-head )

or

curl http://rvm.io/releases/rvm-install-head | bash

How can I pass in extra parameters along with this execution?

Thanks

Do you mean something as simple as `curl http://rvm.io/releases/rvm-install-head -otherparam | bash -moreparams -yetmoreparams`? — sapi, Apr 08 '13 at 05:46
I just find this question is duplicated with this http://stackoverflow.com/questions/4642915/passing-parameters-to-bash-when-executing-a-script-fetched-by-curl?rq=1 — Zhenkai, Apr 08 '13 at 05:46

Add parameters after -s switch.

Example of use:

echo 'echo params count: ${#@}, params: $@' | bash -s param1 param2

Output:

params count: 2, params: param1 param2
