how to make “bash < (curl -s”??

Answer 1

No idea about bash and shell, but here's what ChatGPT said:

The command executes a shell script from the internet using Bash. How it works:

bash <(curl -s https://example.com/script.sh)

Here,

curl -s URL — downloads the script silently (-s = silent mode).

<(...) — process substitution, creates a temporary file-like reference to the output of the command inside.

bash <(...) — runs that downloaded script using Bash.
