Overall, this command is a convenient way to execute a sequence of MySQL commands stored in a script file against a MySQL server. The SQL file I wanted to execute looked like this:- SQL script to bootstrap the DB: - CREATE USER 'x''' IDENTIFIED BY 'x' GRANT ALL PRIVILEGES ON mystore. Then, run two SQL SELECT statements from the SQL script file comparesales.sql . I also needed to execute a SQL file, but the catch was that there wasn't one statement per line, so the accepted answer didn't work for me. The < symbol redirects the contents of the file /tmp/script.sql to the MySQL command-line client so that the script commands can execute on the server. Execute SQL Script Using MySQL Native Interface. be careful with the linked to script a bit-if your script has a code 'comment' like select 1 - do nothing then the script doesn't execute it but treats it like the first half of a longer command concatenated with the new command other side effect-if that's the last thing in your file, it doesn't run it at all.

One key point to note is that all commands will be executed in the order that they appear in the script. More importantly, to run multiple commands, we need to put them into a script file. The mysql command is generally used for interactive sessions, but it’s also capable of executing scripts from the terminal.
