The "sqlite3" command refers to the SQLite command-line shell. SQLite is a lightweight, file-based database management system. The "sqlite3" command allows you to interact with SQLite databases through a command-line interface.

When you run the "sqlite3" command, it opens the SQLite shell, which provides a prompt where you can enter various commands to interact with SQLite databases. These commands may include creating databases, tables, inserting, updating, or deleting data, querying the database, and more.

For example, after running "sqlite3", you can create a new database using the "CREATE DATABASE" command, create tables within the database using the "CREATE TABLE" command, insert data into the tables using the "INSERT INTO" command, execute SQL queries using the SELECT statement, and perform other operations to manage the database.

Overall, the "sqlite3" command is used to access the SQLite shell and execute SQLite-specific commands to manage and interact with SQLite databases.
