# 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
|
|
|
|
```sh
|
|
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
|
|
|
|
```sh
|
|
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
|
|
|
|
```sh
|
|
lotus chain head
|
|
```
|
|
|
|
### Control the logging level
|
|
|
|
```sh
|
|
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`.
|
|
|
|
### Find out what version of Lotus you're running
|
|
|
|
```sh
|
|
lotus version
|
|
```
|
|
|
|
## Managing your accounts
|
|
|
|
### Listing accounts in your wallet
|
|
|
|
```sh
|
|
lotus wallet list
|
|
```
|
|
|
|
### Creating a new account
|
|
|
|
```sh
|
|
lotus wallet new bls
|
|
```
|
|
This command will create a new BLS account in your wallet; these
|
|
addresses start with the prefix `t3`. Running `lotus wallet new secp256k1`
|
|
(or just `lotus wallet new`) will create
|
|
a new Secp256k1 account, which begins with the prefix `t1`.
|
|
|
|
### Getting an account's balance
|
|
|
|
```sh
|
|
lotus wallet balance <address>
|
|
```
|
|
|
|
### Transferring funds
|
|
|
|
```sh
|
|
lotus send --source=<source address> <destination address> <amount>
|
|
```
|
|
This command will transfer `amount` (in attoFIL) from `source address` to `destination address`.
|
|
|
|
### Importing an account into your wallet
|
|
|
|
```sh
|
|
lotus wallet import <path to private key>
|
|
```
|
|
This command will import an account whose private key is saved at the specified file.
|
|
|
|
### Exporting an account from your wallet
|
|
|
|
```sh
|
|
lotus wallet export <address>
|
|
```
|
|
This command will print out the private key of the specified address
|
|
if it is in your wallet. Always be careful with your private key!
