Nushell Integration

Detection uses $env.NU_VERSION (exported to child processes). When present:

  • Facts render as a small table

  • Tips use Nushell builtins (sys, $nu.os-info, $env, df, ps, …)

  • --format nuon emits a record you can from nuon in a pipeline

When not under Nushell, tips stay classic (bash/zsh/pwsh/cmd idioms) and about points you at nushell.sh with install hints. If nu is already on PATH, it tells you to just run it.
