Any arguments starting with "-" must be after a "--" separator.
Options:
--from specifies the source. Source can be: device: this is the default input. The input comes from the live monitoring of one or several processes. At least one of '--remote-pid', '--remote-name', '--remote-job-id', --'remote-job-name', 'run' must be specified. dump: The input comes from stdin which is the log output of one or several programs. The lines in the log which dump syscalls are decoded and replaced by the decoded version. All other lines are unchanged. <path>: playback. Used to replay a session previously recorded with --to <path> (protobuf format). Path gives the name of the file to read. If path is '-' then the standard input is used. This option must be used at most once. --to the session is saved to the specified file (binary protobuf format). When a session is saved, you can replay it using "--from <path>". The raw data is saved. That means that the data saved is independent from what is displayed. --format the display format for the session dump. The available formats are: pretty: the session is pretty printed (with colors). This is the default output if --with is not used. json: the session is printed using a json format. textproto: the session is printed using a text protobuf format. none: nothing is displayed on the standard output (this option only makes sense when used with `--to` or with `--with`). When there is no output, fidlcat is faster (this is better to monitor real time components). This is the default output when --with is used. --with specifies an extra summarized output. summary: at the end of the session, a summary of the session is displayed on the standard output. top: at the end of the session, generate a view that groups the output by process, protocol, and method. The groups are sorted by number of events, so groups with more associated events are listed earlier. group-by-thread: for each thread display a short version of all the events. An equal sign followed by a path can be concatanated to the option to output the result in a file instead of the standard output (for example: --with summary=/tmp/x). This option can be used several times. --with-process-info display the process name, process id and thread id on each line (useful for grep). --stack define the amount of stack frame to display 0: none (default value) 1: call site (1 to 4 levels) 2: full stack frame (adds some overhead) --syscalls a regular expression which selects the syscalls to decode and display. This option can be specified multiple times. By default, only zx_channel_.* syscalls are displayed. To display all the syscalls, use: --syscalls ".*" --exclude-syscalls a regular expression which selects the syscalls to not decode and display. This option can be specified multiple times. To be displayed, a syscall must verify --syscalls and not verify --exclude-syscalls. To display all the syscalls but the zx_handle syscalls, use: --syscalls ".*" --exclude-syscalls "zx_handle_.*" --messages a regular expression which selects the messages to display. To display a message, the method name must satisfy the regexp. This option can be specified multiple times. Message filtering works on the method's fully qualified name. --exclude-messages a regular expression which selects the messages to not display. If a message method name satisfy the regexp, the message is not displayed (even if it satisfies --messages). This option can be specified multiple times. Message filtering works on the method's fully qualified name. --trigger start displaying messages and syscalls only when a message for which the method name satisfies the filter is found. This option can be specified multiple times. Message filtering works on the method's fully qualified name. --thread only display the events for the specified thread. This option can be specified multiple times. By default all the events are displayed. --dump-messages always does a hexadecimal dump of the messages even if we can decode them. --remote-pid the koid of the remote process to trace. -f, --remote-name the <name> of a process. Fidlcat will monitor all existing and future processes whose names includes <name> (<name> is a substring of the process name). This option can be specified multiple times. When used with --remote-job-id or --remote-job-name, only the processes from the selected jobs are taken into account. --extra-name like "--remote-name" but for these processes, monitoring starts only when one of the "--remote-name" or "--remote-component" is launched. Also, fidlcat stops when the last "--remote-name" or "--remote-component" stops, even if some "--extra-name" processes are still running. You must specify at least one filter with "--remote-name" or "--remote-component" if you use this option. This option can be specified multiple times. -c, --remote-component the URL or the moniker of a component for which we want to monitor. All processes running in the component will be monitered. This option can be specified multiple times. --extra-component like "--remote-component" but for these components, monitoring starts only when one of the "--remote-name" or "--remote-component" is launched. Also, fidlcat stops when the last "--remote-name" or "--remote-component" stops, even if some "--extra-component" are still running. You must specify at least one filter with "--remote-name" or "--remote-component" if you use this option. This option can be specified multiple times. --fidl-ir-path add the given path as a repository for FIDL IR, in the form of .fidl.json files. Passing a file adds the given file. Passing a directory adds all of the .fidl.json files in that directory and any directory transitively reachable from there. An argfile contains a newline-separated list of .fidl.json files relative to the directory containing the argfile; passing an argfile (starting with the '@' character) adds all files listed in that argfile. This option can be specified multiple times. --help display usage information

Usage: ffx emu <command> [<args>] Start and manage Fuchsia emulators.
Options:
--help display usage information
Commands:
console [EXPERIMENTAL] Connect to a running Fuchsia emulator's console. list List running Fuchsia emulators. show Show Fuchsia emulator details. start Start the Fuchsia emulator. stop Shut down a running Fuchsia emulator. Notes: The emu command is used to start up, manage, and shut down Fuchsia emulators. The `start` subcommand launches an emulator according to the configuration in the Product Bundle. Once one or more emulators are running, you can use the `list` subcommand to see the name and status of all running emulators, and the `show` subcommand to get a printout of the configuration for a specific emulator. When you're done with an emulator, use the `stop` subcommand to cleanly terminate that emulator. For more information on the Fuchsia emulator, see the Getting Started page at https://fuchsia.dev/fuchsia-src/get-started/set_up_femu.
Usage: ffx emu console [<name>] [--console-type <console-type>] [-c] [-m] [-s] [EXPERIMENTAL] Connect to a running Fuchsia emulator's console. Positional Arguments: name name of the emulator to connect to, as specified to the start command. See a list of available instances by running `ffx emu list`. If no name is specified, and only one emulator is running, it will be selected.
Options:
--console-type selector for which console to attach to. Accepted values are: command machine serial -c, --command attach to the user-interactive command console. Equivalent to "--console-type command". -m, --machine attach to the machine-readable command console. Equivalent to "--console-type machine". -s, --serial attach to the Fuchsia serial console. Equivalent to "--console-type serial". --help display usage information Examples: ffx emu console -s ffx emu console fuchsia-emulator --console-type serial

Usage: ffx emu show [<name>] [--all] [--cmd] [--config] [--net] [--raw] Show Fuchsia emulator details. Positional Arguments: name name of the emulator instance to show details for. See a list of available instances by running `ffx emu list`. If only one instance is running, this defaults to that instance name.
Options:
--all show all of the available details, excluding the raw internal format. --cmd show the command line used to launch the emulator. --config show the configuration in a format consistent with the 'start' command's --config flag. --net switch to show network details. --raw show the entire config output. This is the default output if no other switches are invoked. --help display usage information
Usage: ffx emu start [<product_bundle>] [--accel <accel>] [--config <config>] [--console] [--debugger] [--device <device>] [--device-list] [--dry-run] [--edit] [--engine <engine>] [--gpu <gpu>] [-H] [--hidpi-scaling <hidpi-scaling>] [-c <kernel-args...>] [-l <log>] [-m] [--name <name>] [--net <net>] [--port-map <port-map...>] [--reuse] [-s <startup-timeout>] [-V] Start the Fuchsia emulator. Positional Arguments: product_bundle use named product information from Product Bundle Metadata (PBM). If no product bundle is specified and there is an obvious choice, that will be used (e.g. if there is only one PBM available).
Options:
--accel virtualization acceleration. Valid choices are "none" to disable acceleration, "hyper" to use the host's hypervisor interface (KVM on Linux and HVF on MacOS), or "auto" to use the hypervisor if detected. The default value is "auto". --config specify a configuration file to populate the command line flags for the emulator. Defaults to a Handlebars config specified in the Product Bundle manifest. --console launch the emulator in serial console mode. This redirects the virtual serial port to the host's input/output streams, then maintains a connection to those streams rather than returning control to the host terminal. This is especially useful when the guest is running without networking enabled. --debugger pause on launch and wait for a debugger process to attach before resuming. The guest operating system will not begin execution until a debugger, such as gdb or lldb, attaches to the emulator process and signals the emulator to continue. --device specify the virtual device specification to use from the product bundle. If no device is specified then the first device listed in the PBM is used. A default can be set by running `ffx config set emu.device <type>`. --device-list print the list of available virtual devices. --dry-run sets up the emulation, but doesn't start the emulator. The command line arguments that the current configuration generates will be printed to stdout for review. --edit open the user's default editor to modify the command line flags for the emulator. --engine emulation engine to use for this instance. Allowed values are "femu" which is based on Android Emulator, and "qemu" which uses the version of Qemu packaged with Fuchsia. Default is "femu". This can be overridden by running `ffx config set emu.engine <type>`. --gpu GPU acceleration mode. Allowed values are "host", "guest", "swiftshader_indirect", or "auto". Default is "auto". Note: this is unused when using the "qemu" engine type. See https://developer.android.com/studio/run/emulator-acceleration#command-gpu for details on the available options. This can be overridden by running `ffx config set emu.gpu <type>`. -H, --headless run the emulator without a GUI. The guest system may still initialize graphics drivers, but no graphics interface will be presented to the user. --hidpi-scaling enable pixel scaling on HiDPI devices. Defaults to true for MacOS, false otherwise. -c, --kernel-args experimental(for https://fxbug.dev/95278). Passes the given string to the emulator executable, appended after all other arguments (since duplicated values favor the later value). This means command-line values will override configuration-provided values for any of these kernel arguments. Can be repeated arbitrarily many times for multiple additional kernel arguments. -l, --log store the emulator log at the provided filesystem path. By default, all output goes to a log file in the emulator working directory. The path to this file is printed onscreen during start-up. -m, --monitor launch the emulator in Qemu monitor console mode. See https://qemu-project.gitlab.io/qemu/system/monitor.html for more information on the Qemu monitor console. --name name of this emulator instance. This is used to identify the instance in other commands and tools. Default is "fuchsia-emulator". --net specify the networking mode for the emulator. Allowed values are "none" which disables networking, "tap" which attaches to a Tun/Tap interface, "user" which sets up mapped ports via SLiRP, and "auto" which will check the host system's capabilities and select "tap" if it is available and "user" otherwise. Default is "auto". --port-map specify a host port mapping for user-networking mode. Ignored in other networking modes. Syntax is "--port-map <portname>:<port>". The <portname> must be one of those specified in the virtual device specification. This flag may be repeated for multiple port mappings. --reuse reuse a persistent emulator's state when starting up. If an emulator with the same name as this instance has been previously started and then stopped without cleanup, this instance will reuse the images from the previous instance. If no previous instance is found, or if the old instance is still running, the new emulator will not attempt to start. -s, --startup-timeout the maximum time (in seconds) to wait on an emulator to boot before returning control to the user. A value of 0 will skip the check entirely. Default is 60 seconds. This can be overridden with `ffx config set emu.start.timeout <seconds>`. -V, --verbose enables extra logging for debugging. --help display usage information Examples: ffx emu start ffx emu start workstation_eng.qemu-x64 --name my-emulator --engine femu Notes: The `start` subcommand is the starting point for all emulator interactions. The name provided here will be used for all later interactions to indicate which emulator to target. Emulator names must be unique. The start command will compile all of the necessary configuration for an emulator, launch the emulator, and then store the configuration on disk for future reference. The configuration comes from the Product Bundle, which includes a virtual device specification and a start-up flag template. See https://fuchsia.dev/fuchsia-src/contribute/governance/rfcs/0100_product_metadata for more information.
Usage: ffx emu stop [<name>] [--all] [-p] Shut down a running Fuchsia emulator. Positional Arguments: name name of the emulator to shutdown, as specified to the start command. See a list of available instances by running `ffx emu list`. If no name is specified, and only one emulator is running, it will be terminated.
Options:
--all shut down and clean up all emulator instances running on the device. -p, --persist don't remove the state directory on stop, just terminate the emulator. --help display usage information Examples: ffx emu stop ffx emu stop --all ffx emu stop fuchsia-emulator --persist Notes: By default, the stop command will remove an emulator's on-disk working directory, which contains emulator state, staged image files, etc. Use the --persist flag if you need to leave the working directory intact while shutting down the emulator, for debugging or troubleshooting purposes. The working directory will be left in place, and the emulator will be marked [Inactive] in `ffx emu list` results until stop is called for that instance without the --persist flag.

Notes: The `target` subcommand contains various commands for target management and interaction. Typically, this is the entry workflow for users, allowing for target discovery and provisioning before moving on to `component` or `session` workflows once the system is up and running on the target. Most of the commands depend on the RCS (Remote Control Service) on the target.
Usage: ffx target add <addr> [-n] Make the daemon aware of a specific target Positional Arguments: addr IP of the target.
Options:
-n, --nowait do not wait for a connection to be verified on the Fuchsia device. --help display usage information Examples: To add a remote target forwarded via ssh: $ ffx target add 127.0.0.1:8022 Or to add a target using its IPV6: $ ffx target add fe80::32fd:38ff:fea8:a00a Notes: Manually add a target based on its IP address. The command accepts IPV4 or IPV6 addresses, including a port number: `<addr> = <ip addr:port>`. Typically, the daemon automatically discovers targets as they come online. However, manually adding a target allows for specifying a port number or address, often used for remote workflows. This command will attempt to connect to the target in order to verify that RCS can be used, allowing for typical FFX related workflows. If you do not wish to use this, then you can run use the `--nowait` flag to return immediately. This can be useful for debugging connection issues. If you send SIGINT (Ctrl-C) to the command before the connection to the target is verified, the target will be removed. If RCS cannot be connected to (e.g. some connectivity error is encountered), the target will also be removed.

When --test-file is specified test_args should not be specified.
Options:
-t, --timeout test timeout in seconds --test-file read test url and options from the specified file instead of from the command line. Stdin may be specified by passing `--test-file -`. May not be used in conjunction with `test_args`, `--test-file`, `--test-filter`, `--run-disabled`, `--parallel`, `--max-severity-logs` This option is currently unstable and the format of the file is subject to change. For current details, see test-list.json format at https://fuchsia.googlesource.com/fuchsia/+/refs/heads/main/src/lib/testing/test_list/ --test-filter test filter. Glob pattern for matching tests. Can be specified multiple times to pass in multiple patterns. Tests may be excluded by prepending a '-' to the glob pattern. example: --test-filter glob1 --test-filter glob2 --test-filter -glob3. --run-disabled whether to also run tests that have been marked disabled/ignored by the test author. --filter-ansi whether to filter ANSI escape sequences from output --continue-on-timeout continue running unfinished suites if a suite times out. By default, unfinished suites are immediately terminated if a suite times out. This option is only relevant when multiple suites are run. --stop-after-failures stop running unfinished suites after the number of provided failures has occurred. By default, all suites are run to completion if a suite fails. --parallel run tests in parallel, up to the number provided. --count number of times to run the test. By default run 1 time. If an iteration of the test times out, no further iterations are executed. --min-severity-logs when set, only logs with a severity equal to the given one or higher will be printed. --max-severity-logs when set, the test will fail if any log with a higher severity is emitted. --show-full-moniker-in-logs when set, shows the full moniker in unstructured log output. --output-directory when set, output test results to the specified directory. --experimental-parallel-execution enables experimental parallel test scheduler. The provided number specifies the max number of test suites to run in parallel. If the value provided is 0, a default value will be chosen by the server implementation. --disable-output-directory when set, disables structured output to a directory. --help display usage information Notes: Runs test suites implementing the `fuchsia.test.Suite` protocol. Tests are specified either as a command line argument, or via JSON file. For example, when specifying a test via command line: ffx test run fuchsia-pkg://fuchsia.com/my_test#meta/my_test.cm When specifying a test via command line and passing arguments to the test: ffx test run fuchsia-pkg://fuchsia.com/my_test#meta/my_test.cm -- arg1 arg2 Specifying tests via JSON file is currently unstable, but may be done with the --test-file option. Note that if running multiple iterations of a test and an iteration times out, no further iterations will be executed.

Usage: ffx trace start [--buffering-mode <buffering-mode>] [--buffer-size <buffer-size>] [--categories <categories>] [--duration <duration>] [--output <output>] [--background] [--trigger <trigger...>] Record a trace.
Options:
--buffering-mode the buffering to use on the trace. Defaults to "oneshot". Accepted values are "oneshot," "circular," and "streaming." --buffer-size size of per-provider trace buffer in MB. Defaults to 4. --categories comma-separated list of categories to enable. Defaults to "app,audio,benchmark,blobfs,gfx,input,kernel:meta, kernel:sched,ledger,magma,minfs,modular,view,flutter, dart,dart:compiler,dart:dart,dart:debugger,dart:embedder, dart:gc,dart:isolate,dart:profiler,dart:vm" --duration duration of trace capture in seconds. --output name of output trace file. Defaults to trace.fxt. --background whether to run the trace in the background. Defaults to false, which means the trace will run in "interactive" mode. --trigger a trigger consists of an alert leading to an action. An alert is written into the code being traced, and an action here is what to do when the alert has happened. The list of supported actions are: 'terminate'. The expected format is "<alert>:<action>" ex: -trigger "my_alert:terminate" This can be used with a duration, but keep in mind that this introduces a race between whether the alert leads to an action, and when the trace stops from the duration being reached. Triggers can only be used in the background outside of interactive mode. --help display usage information
