All commands below require only nuts to be installed. Dependencies, JVM versions, and platform binaries are resolved and provisioned automatically. If a required JVM version is not found, nuts will download and install it into the workspace transparently.

nsh — structured output from shell commands

nsh is a bash-compatible shell shipped with nuts, extended with structured output formats:

nuts nsh -c "ls --json"
nuts nsh -c "ls --table"
nuts nsh -c "ls --tree"
nuts nsh -c "ls --xml"
nuts nsh -c "ls --yaml"
nuts nsh -c "ls --tson"

nsh — cross-protocol file operations

The nuts runtime exposes a unified path model across all protocols. Every nuts-aware tool inherits it — not just nsh.

# copy from HTTP to a remote server over SSH
nuts nsh -c "cp http://files.example.com/app.jar ssh://user@prod-server/deploys/"

# tail a remote log file
nuts nsh -c "cat ssh://user@myserver/var/log/myapp.log | grep ERROR"

# copy between two remote servers without a local intermediate
nuts nsh -c "cp ssh://user@server1/data/dump.sql ssh://user@server2/restore/dump.sql"

Supported protocols: http, https, ssh, htmlfs, dotfilefs, local paths.
