# nu-bang Use Pi's `!` and `!!` input with Nushell syntax instead of your usual shell.  ## Use Install `nu`, open Pi, then type a bang command such as: ```text !ls | where type == file ``` Pi runs bang commands through Nushell and offers Nushell completions while you type them. Use `!!` as you normally would to repeat a bang command. No slash command or activation step is needed. Pi recognizes common full-screen editors, pagers, and terminal interfaces such as `nvim`, `less`, `lazygit`, and interactive Git commands. It temporarily hands those commands the terminal, then returns to Pi. Prefix any command with `!i` to force that behavior: ```text !i my-interactive-command ``` Interactive bang commands need Pi's terminal UI. They do not run in print or RPC mode. By default, Pi finds `nu` on `PATH`. Set `nu-bang.command` only when Nushell has a different executable name or location: ```json { "nu-bang": { "command": "/usr/bin/nu" } } ``` If this setting is invalid, Pi warns and uses `nu` from `PATH`.
