Copy output of bash command to system clipboard?

Question

If I run:

:w !node

It will take my current buffer and send it to stdin and run the code in node.

If I run:

:redir @+ | echo "bob" | redir END

It ends up on the system clipboard.

But if I want to copy the output to the clipboard, by running:

:redir @+ | w !node | redir END

It seems the input from the current buffer does not reach node, and that it tries to run redir as a command from bash for some reason.

:redir @+ | w !node | redir END
/bin/bash: redir: command not found
events.js:141
      throw er; // Unhandled 'error' event
      ^

Error: write EPIPE
    at exports._errnoException (util.js:907:11)
    at WriteWrap.afterWrite (net.js:790:14)

shell returned 127

Is there some other way to do this?

Answer 1

Everything after ! will be a command, including |. So what you're running is:

:redir @+
:w !node | redir END

This makes sense, since using | is shell commands is common to pipe output.

The easiest workaround is to use multiple lines:

:redir @+
:w !node
:redir END

or you can use :execute to work around this:

:redir @+ | :exe 'w !node' | redir END
