Alias:

ip

. Run

unity install-path --help

for the current option list, including flags to display or update the path.

Open a project

Open a Unity project, resolving the Editor version declared by the project.


unity open <path>

You can omit the

open

keyword when the first argument is a path:


unity open ./MyProjectunity ./MyProject       # equivalent

Manage projects in the Hub registry

Manage the list of Unity projects the Hub knows about, so both the Hub UI and the CLI can find and open them.


unity projects [subcommand] [options]

Alias:

. Run

unity projects --help

to check the available commands and options in your installed CLI version.

The

auth

command manages your Unity account session.


unity auth loginunity auth statusunity auth logout

Command	Description
`unity auth login`	Opens a browser-based sign-in flow.
`unity auth status`	Prints the current signed-in user, if any.
`unity auth logout`	Signs out of the current session.

Change the CLI display language

Show the current CLI display language, or change it to a supported language.


unity language [options]

Alias:

lang

. Run

unity language --help

for the list of supported languages and the exact option names.

Output formats and automation

The CLI chooses a default output format based on the context and supports explicit formats for automation.

Format selection

Format	Selected when	Notes
`human`	Output goes to an interactive terminal.	Colorized, animated progress, aligned columns.
`tsv`	Output goes to a pipe or file.	Tab-separated, one record per line. Machine-parseable.
`json`	You set `--format json` (or `--json` ).	Structured output for use with `jq` and other tools. Uses a standard envelope with `success` , `command` , `data` , `errors` , and `warnings` .
`ndjson`	You set `--format ndjson` .	One JSON object per line. Long-running commands, such as `install` , stream typed progress frames and end with a result frame.

Select a format explicitly with the global flag:


unity editors -i --format jsonunity editors -i --format tsvunity install lts --format ndjson

注

--json

is accepted on every command as a global shorthand for

--format json

. When you supply both,

--format

takes precedence.

ヒント

When you pipe CLI output, the default format changes to tab-separated values (TSV). If a script expects human-readable text, set

--format human

explicitly, or parse TSV, JSON, or NDJSON instead. Use

json

for a single buffered result and

ndjson

when you also want streamed progress frames from long-running commands.

Error output

The CLI writes errors and diagnostic messages to

stderr

, leaving

stdout

free for data output. In JSON mode, the CLI emits errors as

{"error": "..."}

stderr

To capture both streams in a shell:


unity install 6000.3.7f1 > install.log 2>&1

Exit codes

Code	Meaning
`0`	Success.
`1`	A general error occurred. Inspect `stderr` for details.
`2`	Usage error: invalid flags, invalid option values, or missing required arguments.
`3`	Authentication or authorization failure, such as a rejected sign-in or an expired session.
`4`	Configuration required: the arguments are valid, but a required preference or context isn't set.
`6`	The command's primary operation failed, for example an Editor install failed, tests failed, or the Editor exited with an error.
`130`	The command was interrupted with Ctrl+C ( `SIGINT` ).
`143`	The command was terminated with `SIGTERM` , for example by `kill` or a CI runner timeout.

Environment variables

Global CLI options have environment variable equivalents, and some behaviors are controlled only through the environment. A command-line flag takes precedence over its environment variable.

Variable	Effect
`UNITY_FORMAT`	Default output format ( `human` , `json` , `tsv` , or `ndjson` ). `HUB_FORMAT` remains supported as an alias.
`UNITY_QUIET`	Suppress non-essential output, like `--quiet` .
`UNITY_NO_BANNER`	Suppress the Unity banner, like `--no-banner` .
`UNITY_NON_INTERACTIVE`	Disable interactive prompts, like `--non-interactive` .
`UNITY_PROJECT_PATH`	Default Unity project path for commands that accept `--project-path` .
`UNITY_CLOUD_ORG`	Default Unity Cloud organization for commands that accept `--cloud-org` .
`UNITY_PROXY`	Proxy server URL, like `--proxy` .
`UNITY_LOG_PROXY`	Log one redacted entry per outbound request for proxy troubleshooting, like `--log-proxy` .
`UNITY_INSTALL_RETRIES`	Number of retries for module downloads that fail intermittently, like `--retries` . `0` disables retries.
`UNITY_NO_ELEVATE`	Windows only. Skip the elevated (UAC) install helper, like `--no-elevate` .
`UNITY_NO_UPDATE_CHECK`	Disable the background check for CLI updates.
`UNITY_NO_CRASH_REPORT`	Disable anonymous crash and error reporting.
`UNITY_NO_CONSENT_PROMPT`	Suppress the one-time first-run analytics consent prompt without recording a choice.
`UNITY_SERVICE_ACCOUNT_ID` , `UNITY_SERVICE_ACCOUNT_SECRET`	Authenticate as a Unity service account for unattended workflows. Set both.

Progress output

Long-running commands (such as

install

) render animated progress bars on an interactive terminal and a static summary when complete. Progress output is for human readers. Don't parse it in scripts. For a machine-readable result, use

--format json

; to also stream machine-readable progress updates while the command runs, use

--format ndjson

, which emits typed progress frames followed by a final result frame.

Log locations

The CLI writes its own log file,

cli-log.json

, in the shared Unity Hub logs directory. Read and follow it with

unity logs

, or include it in a diagnostic snapshot with

unity doctor

Platform	Path
Windows	`%UserProfile%\AppData\Roaming\UnityHub\logs`
macOS	`~/Library/Application Support/UnityHub/logs`
Linux	`~/.config/UnityHub/logs`

You can also open the log folder from the Hub: Account > Help and Support > Logs.

Migrate from the Hub CLI

If you have scripts targeting the CLI embedded in the Unity Hub desktop application (invoked with

-- --headless

), the following tables summarize the behavioral and syntactic differences. For full Hub CLI syntax, refer to Hub CLI reference.

Invocation

	Hub CLI	Unity CLI
How to run	`"Unity Hub.exe" -- --headless <command>`	`unity <command>`
Dependency	Requires the full Unity Hub desktop application.	Standalone binary; no Hub installation required.

Command and flag changes

Area	Hub CLI	Unity CLI
`install` version	`--version` / `-v <version>` (required flag)	`[version]` (optional positional argument)
`install-modules` editor version	`--version` / `-v <version>` (required)	`-e, --editor-version <version>` (optional)
`install-modules` module	`--module` / `-m <id>` (required)	`-m, --module <id>` (optional)
`editors` add local Editor	`editors --add <path>` (flag)	`editors add <path...>` (command; accepts multiple paths)
`-v` on `install`	Editor version	Reserved. `-V` prints the CLI version.
`help` command	Platform-specific help text files	Replaced by `--help` on every command.

Output and errors

Area	Hub CLI	Unity CLI
Default output	Plain text, always	`human` on an interactive terminal; `tsv` when piped
Structured output	`--json` per command (where supported)	Global `--format json` ( `--json` kept for compatibility)
Errors	Written to `stdout`	Written to `stderr` (JSON errors: `{"error": "..."}` on `stderr` )
Progress	Plain text lines, for example `downloading 23.50%`	Animated progress bar; static summary on completion
Exit codes	`0` success, `1` error	Differentiated codes for usage, auth, and command failures. Refer to Exit codes.

Removed global flags

These Hub CLI flags have no equivalent in the Unity CLI:

--headless

--errors

--silent

--logLevel

-l

--bugReporter

--debugMode

--inspect

--userEmail

--theme

--editorLicense

--servicesUrlInterval

--cloudEnvironment

New commands

The Unity CLI adds many commands not in the Hub CLI, including

auth

open

projects

uninstall

upgrade

build

test

license

shell

, and

mcp

. Refer to the Commands tables for the full list. The path shorthand

unity ./MyProject

is equivalent to

unity open ./MyProject

Impact summary

重要

Review existing scripts and continuous integration (CI) pipelines before switching. The following items describe the areas most likely to require changes.

High: scripts that fail without updates

Replace
```
-- --headless
```
invocations with
```
unity
```
.
Replace
```
install -v <version>
```
with
```
install <version>
```
(positional).

Replace

install-modules --version

-v

with

--editor-version

-e

Replace
```
editors --add
```
with
```
editors add
```
.

Medium: behavior changes that can produce wrong results

Piped
```
stdout
```
defaults to TSV, not plain text.
Errors go to
```
stderr
```
, not
```
stdout
```
.
Progress output format changed. Don't parse it.

Low: additive changes that don't break existing usage

New commands:
```
auth
```
,
```
open
```
,
```
projects
```
,
```
uninstall
```
,
```
upgrade
```
.
New flags such as
```
--verbose
```
,
```
--list
```
, and
```
--all
```
.
Version aliases:
```
latest
```
,
```
lts
```
,
```
default
```
, and short majors.
New exit code
```
130
```
for user cancellation.
