## OPTIONS

### Special Options

<dl>

<dt class="option-term" id="option-cargo--V"><a class="option-anchor" href="#option-cargo--V"></a><code>-V</code></dt>
<dt class="option-term" id="option-cargo---version"><a class="option-anchor" href="#option-cargo---version"></a><code>--version</code></dt>
<dd class="option-desc">Print version info and exit. If used with <code>--verbose</code>, prints extra
information.</dd>


<dt class="option-term" id="option-cargo---list"><a class="option-anchor" href="#option-cargo---list"></a><code>--list</code></dt>
<dd class="option-desc">List all installed Cargo subcommands. If used with <code>--verbose</code>, prints extra
information.</dd>


<dt class="option-term" id="option-cargo---explain"><a class="option-anchor" href="#option-cargo---explain"></a><code>--explain</code> <em>code</em></dt>
<dd class="option-desc">Run <code>rustc --explain CODE</code> which will print out a detailed explanation of an
error message (for example, <code>E0004</code>).</dd>


</dl>

### Display Options

<dl>

<dt class="option-term" id="option-cargo--v"><a class="option-anchor" href="#option-cargo--v"></a><code>-v</code></dt>
<dt class="option-term" id="option-cargo---verbose"><a class="option-anchor" href="#option-cargo---verbose"></a><code>--verbose</code></dt>
<dd class="option-desc">Use verbose output. May be specified twice for “very verbose” output which
includes extra output such as dependency warnings and build script output.
May also be specified with the <code>term.verbose</code>
<a href="../reference/config.html">config value</a>.</dd>


<dt class="option-term" id="option-cargo--q"><a class="option-anchor" href="#option-cargo--q"></a><code>-q</code></dt>
<dt class="option-term" id="option-cargo---quiet"><a class="option-anchor" href="#option-cargo---quiet"></a><code>--quiet</code></dt>
<dd class="option-desc">Do not print cargo log messages.
May also be specified with the <code>term.quiet</code>
<a href="../reference/config.html">config value</a>.</dd>


<dt class="option-term" id="option-cargo---color"><a class="option-anchor" href="#option-cargo---color"></a><code>--color</code> <em>when</em></dt>
<dd class="option-desc">Control when colored output is used. Valid values:</p>
<ul>
<li><code>auto</code> (default): Automatically detect if color support is available on the
terminal.</li>
<li><code>always</code>: Always display colors.</li>
<li><code>never</code>: Never display colors.</li>
</ul>
<p>May also be specified with the <code>term.color</code>
<a href="../reference/config.html">config value</a>.</dd>



</dl>

### Manifest Options

<dl>
<dt class="option-term" id="option-cargo---frozen"><a class="option-anchor" href="#option-cargo---frozen"></a><code>--frozen</code></dt>
<dt class="option-term" id="option-cargo---locked"><a class="option-anchor" href="#option-cargo---locked"></a><code>--locked</code></dt>
<dd class="option-desc">Either of these flags requires that the <code>Cargo.lock</code> file is
up-to-date. If the lock file is missing, or it needs to be updated, Cargo will
exit with an error. The <code>--frozen</code> flag also prevents Cargo from
attempting to access the network to determine if it is out-of-date.</p>
<p>These may be used in environments where you want to assert that the
<code>Cargo.lock</code> file is up-to-date (such as a CI build) or want to avoid network
access.</dd>


<dt class="option-term" id="option-cargo---offline"><a class="option-anchor" href="#option-cargo---offline"></a><code>--offline</code></dt>
<dd class="option-desc">Prevents Cargo from accessing the network for any reason. Without this
flag, Cargo will stop with an error if it needs to access the network and
the network is not available. With this flag, Cargo will attempt to
proceed without the network if possible.</p>
<p>Beware that this may result in different dependency resolution than online
mode. Cargo will restrict itself to crates that are downloaded locally, even
if there might be a newer version as indicated in the local copy of the index.
See the <a href="cargo-fetch.html">cargo-fetch(1)</a> command to download dependencies before going
offline.</p>
<p>May also be specified with the <code>net.offline</code> <a href="../reference/config.html">config value</a>.</dd>


</dl>

### Common Options

<dl>

<dt class="option-term" id="option-cargo-+toolchain"><a class="option-anchor" href="#option-cargo-+toolchain"></a><code>+</code><em>toolchain</em></dt>
<dd class="option-desc">If Cargo has been installed with rustup, and the first argument to <code>cargo</code>
begins with <code>+</code>, it will be interpreted as a rustup toolchain name (such
as <code>+stable</code> or <code>+nightly</code>).
See the <a href="https://rust-lang.github.io/rustup/overrides.html">rustup documentation</a>
for more information about how toolchain overrides work.</dd>


<dt class="option-term" id="option-cargo---config"><a class="option-anchor" href="#option-cargo---config"></a><code>--config</code> <em>KEY=VALUE</em> or <em>PATH</em></dt>
<dd class="option-desc">Overrides a Cargo configuration value. The argument should be in TOML syntax of <code>KEY=VALUE</code>,
or provided as a path to an extra configuration file. This flag may be specified multiple times.
See the <a href="../reference/config.html#command-line-overrides">command-line overrides section</a> for more information.</dd>


<dt class="option-term" id="option-cargo--C"><a class="option-anchor" href="#option-cargo--C"></a><code>-C</code> <em>PATH</em></dt>
<dd class="option-desc">Changes the current working directory before executing any specified operations. This affects
things like where cargo looks by default for the project manifest (<code>Cargo.toml</code>), as well as
the directories searched for discovering <code>.cargo/config.toml</code>, for example. This option must
appear before the command name, for example <code>cargo -C path/to/my-project build</code>.</p>
<p>This option is only available on the <a href="https://doc.rust-lang.org/book/appendix-07-nightly-rust.html">nightly
channel</a> and
requires the <code>-Z unstable-options</code> flag to enable (see
<a href="https://github.com/rust-lang/cargo/issues/10098">#10098</a>).</dd>


<dt class="option-term" id="option-cargo--h"><a class="option-anchor" href="#option-cargo--h"></a><code>-h</code></dt>
<dt class="option-term" id="option-cargo---help"><a class="option-anchor" href="#option-cargo---help"></a><code>--help</code></dt>
<dd class="option-desc">Prints help information.</dd>


<dt class="option-term" id="option-cargo--Z"><a class="option-anchor" href="#option-cargo--Z"></a><code>-Z</code> <em>flag</em></dt>
<dd class="option-desc">Unstable (nightly-only) flags to Cargo. Run <code>cargo -Z help</code> for details.</dd>


</dl>


## ENVIRONMENT

See [the reference](../reference/environment-variables.html) for
details on environment variables that Cargo reads.


## EXIT STATUS

* `0`: Cargo succeeded.
* `101`: Cargo failed to complete.


## FILES

`~/.cargo/`\
&nbsp;&nbsp;&nbsp;&nbsp;Default location for Cargo's "home" directory where it
stores various files. The location can be changed with the `CARGO_HOME`
environment variable.

`$CARGO_HOME/bin/`\
&nbsp;&nbsp;&nbsp;&nbsp;Binaries installed by [cargo-install(1)](cargo-install.html) will be located here. If using
[rustup], executables distributed with Rust are also located here.

`$CARGO_HOME/config.toml`\
&nbsp;&nbsp;&nbsp;&nbsp;The global configuration file. See [the reference](../reference/config.html)
for more information about configuration files.

`.cargo/config.toml`\
&nbsp;&nbsp;&nbsp;&nbsp;Cargo automatically searches for a file named `.cargo/config.toml` in the
current directory, and all parent directories. These configuration files
will be merged with the global configuration file.

`$CARGO_HOME/credentials.toml`\
&nbsp;&nbsp;&nbsp;&nbsp;Private authentication information for logging in to a registry.

`$CARGO_HOME/registry/`\
&nbsp;&nbsp;&nbsp;&nbsp;This directory contains cached downloads of the registry index and any
downloaded dependencies.

`$CARGO_HOME/git/`\
&nbsp;&nbsp;&nbsp;&nbsp;This directory contains cached downloads of git dependencies.

Please note that the internal structure of the `$CARGO_HOME` directory is not
stable yet and may be subject to change.

## EXAMPLES

1. Build a local package and all of its dependencies:

cargo build

2. Build a package with optimizations:

cargo build --release

3. Run tests for a cross-compiled target:

cargo test --target i686-unknown-linux-gnu

4. Create a new package that builds an executable:

cargo new foobar

5. Create a package in the current directory:

mkdir foo && cd foo
cargo init .

6. Learn about a command's options and usage:

cargo help clean
