Redirecting output into existing (g)vim instance

Question

Is it possible to redirect the output of a process (in bash) into an existing instance of (g)vim?

Something like:

cat myfile1.txt | awk 'print $1' | gvim -

Then I might start a new window inside my vim with :vne and want to fill it with the output from some other process.

Answer 1

Your example works but it can't be used as is from your terminal to open a second output in a second window.

You can put the output of your command in the active buffer from within Vim itself with

:read !cat myfile1.txt | awk 'print $1'

That's the simplest solution I can think of.

You can also use GVim as a server and send it your output, see :h clientserver.
