What happened?

The script doesn't work when being piped or run with process substitution. This causes the following to fail:

curl -fsSL https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh | bash

And:

bash <(curl -fsSL https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh)

The following lines cause the issue:

constructor/constructor/header.sh

Lines 19 to 22 in 84995c8

	if ! echo "$0" | grep '\.sh$' > /dev/null; then
	printf 'Please run using "bash"/"dash"/"sh"/"zsh", but not "." or "source".\n' >&2
	return 1
	fi

I think the intent here was to prevent source from being used. I am not sure if piping was supposed to be prevented too. Some might say it's a bad practice and it should be discouraged...

Pinging @conda/constructor for their opinion too.
