recently i stumpled over vim :terminal mode. i am really exited about that. now i wanted to ask, how i can create a mapping, which sends a command, including a pipe symbol to :terminal? it should look like this:

nnoremap <leader>hcu :term echo "hello" | grep "ll"<CR>

But gives me something like this: https://i.imgur.com/kFdYzgF.png

Any hints, on how i can use commands like this with the :term command?

    However, there is one noteworthy aspect that is not covered here. The command you tell the :term command to be run, won't be processed by the shell, so output redirection like using a | (pipe) cannot work. The :term command expects the command provided to be executed directly (see also this question). May 14 '19 at 6:02

    So you have to provide the shell command to be run directly and make sure to use double quotes to quote the necessary parts, as single quotes might not always work. May 14 '19 at 6:02
