CARGO-CLEAN(1) General Commands Manual CARGO-CLEAN(1)
NAME
cargo-clean -- Remove generated artifacts
SYNOPSIS
cargo clean [options]
DESCRIPTION
Remove artifacts from the target directory that Cargo has generated in
the past.
With no options, cargo clean will delete the entire target directory.
OPTIONS
Package Selection
When no packages are selected, all packages and all dependencies in the
workspace are cleaned.
-p spec, --package spec
Clean only the specified packages. This flag may be specified
multiple times. See cargo-pkgid(1) for the SPEC format.
Clean Options
--dry-run
Displays a summary of what would be deleted without deleting
anything. Use with --verbose to display the actual files that would
be deleted.
--doc
This option will cause cargo clean to remove only the doc directory
in the target directory.
--release
Remove all artifacts in the release directory.
--profile name
Remove all artifacts in the directory with the given profile name.
--target-dir directory
Directory for all generated artifacts and intermediate files. May
also be specified with the CARGO_TARGET_DIR environment variable,
or the build.target-dir config value
<https://doc.rust-lang.org/cargo/reference/config.html>. Defaults
to target in the root of the workspace.
--target triple
Clean for the given architecture. The default is the host
architecture. The general format of the triple is
<arch><sub>-<vendor>-<sys>-<abi>. Run rustc --print target-list for
a list of supported targets. This flag may be specified multiple
times.
This may also be specified with the build.target config value
<https://doc.rust-lang.org/cargo/reference/config.html>.
Note that specifying this flag makes Cargo run in a different mode
where the target artifacts are placed in a separate directory. See
the build cache
<https://doc.rust-lang.org/cargo/reference/build-cache.html>
documentation for more details.
Display Options
-v, --verbose
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 term.verbose
config value
<https://doc.rust-lang.org/cargo/reference/config.html>.
-q, --quiet
Do not print cargo log messages. May also be specified with the
term.quiet config value
<https://doc.rust-lang.org/cargo/reference/config.html>.
--color when
Control when colored output is used. Valid values:
o auto (default): Automatically detect if color support is
available on the terminal.
o always: Always display colors.
o never: Never display colors.
May also be specified with the term.color config value
<https://doc.rust-lang.org/cargo/reference/config.html>.
Manifest Options
--manifest-path path
Path to the Cargo.toml file. By default, Cargo searches for the
Cargo.toml file in the current directory or any parent directory.
--locked
Asserts that the exact same dependencies and versions are used as
when the existing Cargo.lock file was originally generated. Cargo
will exit with an error when either of the following scenarios
arises:
o The lock file is missing.
o Cargo attempted to change the lock file due to a different
dependency resolution.
It may be used in environments where deterministic builds are
desired, such as in CI pipelines.
--offline
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.
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 cargo-fetch(1)
command to download dependencies before going offline.
May also be specified with the net.offline config value
<https://doc.rust-lang.org/cargo/reference/config.html>.
--frozen
Equivalent to specifying both --locked and --offline.
--lockfile-path PATH
Changes the path of the lockfile from the default
(<workspace_root>/Cargo.lock) to PATH. PATH must end with
Cargo.lock (e.g. --lockfile-path
/tmp/temporary-lockfile/Cargo.lock). Note that providing
--lockfile-path will ignore existing lockfile at the default path,
and instead will either use the lockfile from PATH, or write a new
lockfile into the provided PATH if it doesn't exist. This flag can
be used to run most commands in read-only directories, writing
lockfile into the provided PATH.
This option is only available on the nightly channel
<https://doc.rust-lang.org/book/appendix-07-nightly-rust.html> and
requires the -Z unstable-options flag to enable (see #14421
<https://github.com/rust-lang/cargo/issues/14421>).
Common Options
+toolchain
If Cargo has been installed with rustup, and the first argument to
cargo begins with +, it will be interpreted as a rustup toolchain
name (such as +stable or +nightly). See the rustup documentation
<https://rust-lang.github.io/rustup/overrides.html> for more
information about how toolchain overrides work.
--config KEY=VALUE or PATH
Overrides a Cargo configuration value. The argument should be in
TOML syntax of KEY=VALUE, or provided as a path to an extra
configuration file. This flag may be specified multiple times. See
the command-line overrides section
<https://doc.rust-lang.org/cargo/reference/config.html#command-line-overrides>
for more information.
-C PATH
Changes the current working directory before executing any
specified operations. This affects things like where cargo looks by
default for the project manifest (Cargo.toml), as well as the
directories searched for discovering .cargo/config.toml, for
example. This option must appear before the command name, for
example cargo -C path/to/my-project build.
This option is only available on the nightly channel
<https://doc.rust-lang.org/book/appendix-07-nightly-rust.html> and
requires the -Z unstable-options flag to enable (see #10098
<https://github.com/rust-lang/cargo/issues/10098>).
-h, --help
Prints help information.
-Z flag
Unstable (nightly-only) flags to Cargo. Run cargo -Z help for
details.
ENVIRONMENT
See the reference
<https://doc.rust-lang.org/cargo/reference/environment-variables.html>
for details on environment variables that Cargo reads.
EXIT STATUS
o 0: Cargo succeeded.
o 101: Cargo failed to complete.
EXAMPLES
1. Remove the entire target directory:
cargo clean
2. Remove only the release artifacts:
cargo clean --release
