Is there a way to pass arbitrary text to Vim?

Question

I want a way to pass some literal text to Vim. I've seen that it can read from stdin with the "-" argument, so you can pipe things to it, e.g. the output of other commands.

But is there a way to pass any text into it like

vim - "Here's some random text"

and open Vim with that string in the buffer?

It complains if I try this command...

Answer 1

echo string | vim -

Answer 2

cat some_file | vim -

This is the correct way to pipe into vim.

Answer 3

$ echo "Here's some random text" | vim -
