Ethereum Client geth Command Usage-parameter details

Geth is the most commonly used tool (prerequisite development tool) in the development of [Ethereum Smart Contract] (HTTP://XC.HUBWIZ.COM/COURSE/5ABBB7ACC02E6B6A59171DD6), a multi-purpose command-line tool. Familiarity with Geth can allow us to have better efficiency, and we can collect them as a manual for Geth command usage. This article is mainly for the translation of Geth Help, based on the latest Geth 1.7.3-stable version. If you don't know what Geth is, read the introductory article first: [What is Ethereum?] What is a smart contract? ] (https://blog.csdn.net/mongo_node/article/details/80491713) to the beginning of the text. # # # command usage **geth [options] command [command options] [parameters ...] * * Version: 1.7.3-stable### command: Account Admin Attach start interactive javascrip{filter}t environment (connect to node) Bug escalation bug issuesconsole start interactive javascrip{filter} T environment copydb Create a local chain from a folder dump dump (analysis) a specific block store dumpconfig display configuration values export a blockchain to a file import imports a blockchain file init starts and initializes a new Genesis block JS Executes the specified javascrip{filter}t file (multiple) license display license Information Makecache generate Ethash validate cache (for testing) Makedag generate Ethash Mining dag (for testing) monitor Monitor and visualize node metrics removedb Delete Blockchain and state database version print build number wallet manage Ethereum presale wallet help,h show a command or help a command list # # # Ethereum option:--config value TOML configuration file--datadir "XXX" database and keystore key data directory--keystore keystore storage directory (default in datadir)--NOUSB disable monitoring and management of USB hardware wallet--networkid Value network identifier (integer, 1=frontier, 2=morden (deprecated), 3=ropsten, 4=rinkeby) (default: 1)--testnet Ropsten Network: Pre-configured POW (proof-of-work) test network--rinkeby Rinkeby Network: Pre-configured POA (proof-of-authority) test network--syncmode "Fast" sync mode ("Fast", "full", or "light")--ethstats Value escalated Ethstats service URL (nodename:secret@host:port)--identity Value custom node name--lightserv value allows Les request time maximum percentage (0–90) ( Default value: 0)--lightpeers value max Les client peers number (default:)--lightkdf reduce key-derivation ram&cpu with KDF strength consumption use the # # Developer (mode) Option: --dev uses the POA consensus network to pre-allocate a developer account by default and automatically opens mining. --dev.period value Developer mode Mining cycle (0 = when trading only) (default: 0) # # Ethash option:--ethash.cachedir Ethash Validate cache Directory (default = DataDir directory)--ETHASH.CAC Hesinmem value The number of recent Ethash caches saved in memory (16MB per cache) (default: 2)--ethash.cachesondisk value The number of recent Ethash caches saved on disk (16MB per cache) (default: 3)- -ethash.dagdir "" Ethash DAGs directory (default = user hom directory)--ethash.dagsinmem value The number of recent Ethash DAGs saved in memory (per 1GB or more) (default: 1)--ethash.
