You can pipe text into vim directly from stdin. This can be helpful if you want to edit the output of a long bash command, or if you want to see what an installation script contains before piping it into bash.
curl -fsSL https://raw.github.com/cknadler/vim-anywhere/master/install | vim -
The key is to use the
- after the
vim command to make it read from stdin. This will open a new buffer with the output of the previous command.
