What is Cleos Command Line Interface (CLI)?

The Cleos Command Line Interface (CLI) utilizes lines of text to process commands on the EOSIO blockchain platform. Cleos simplifies the development process for software engineers by giving them access to specific developer tools to interact with EOSIO blockchains. The CLI is used for reading data from the blockchain, sending new transactions, and to test and deploy smart contracts. Cleos interacts with Keosd, Nodeos and other components of the EOSIO ecosystem.
