Lotus Command Line Interface
The Command Line Interface (CLI) is a convenient way to interact with a Lotus node. You can use the CLI to operate your node, get information about the blockchain, manage your accounts and transfer funds, create storage deals, and much more!
The CLI is intended to be self-documenting, so when in doubt, simply add --help
to whatever command you're trying to run! This will also display all of the
input parameters that can be provided to a command.
We highlight some of the commonly used features of the CLI below. All CLI commands should be run from the home directory of the Lotus project.
Operating a Lotus node
Starting up a node
lotus daemon
This command will start up your Lotus node, with its API port open at 1234.
You can pass --api=<number> to use a different port.
Checking your sync progress
lotus sync status
This command will print your current tipset height under Height, and the target tipset height
under Taregt.
You can also run lotus sync wait to get constant updates on your sync progress.
Getting the head tipset
lotus chain head
Control the logging level
lotus log set-level
This command can be used to toggle the logging levels of the different
systems of a Lotus node. In decreasing order
of logging detail, the levels are debug, info, warn, and error.
As an example,
to set the chain and blocksync to log at the debug level, run
lotus log set-level --system chain --system blocksync debug.
To see the various logging system, run lotus log list.
