How to Run MySQL/MariaDB Queries Directly from the Linux Command Line

If you are in charge of managing a database server, from time to time you may need to run a query and inspect it carefully. While you can do that from the MySQL / MariaDB shell, but this tip will allow you to execute the MySQL/MariaDB Queries directly using the Linux command line AND save the output to a file for later inspection (this is particularly useful if the query return lots of records).

Let us look at some simple examples of running queries directly from the command line before we can move to a more advanced query.

To view all the databases on your server, you can issue the following command:

# mysql -u root -p -e "show databases;"

Next, to create a database table named tutorials in the database tecmintdb, run the command below:

$ mysql -u root -p -e "USE tecmintdb; CREATE TABLE tutorials(tut_id INT NOT NULL AUTO_INCREMENT, tut_title VARCHAR(100) NOT NULL, tut_author VARCHAR(40) NOT NULL, submissoin_date DATE, PRIMARY KEY (tut_id));"

We will use the following command and pipe the output to the tee command followed by the filename where we want to store the output.

For illustration, we will use a database named employees and a simple join between the employees and salaries tables. In your own case, just type the SQL query between the quotes and hit Enter.

Note that you will be prompted to enter the password for the database user:

# mysql -u root -p -e "USE employees; SELECT DISTINCT A.first_name, A.last_name FROM employees A JOIN salaries B ON A.emp_no = B.emp_no WHERE hire_date < '1985-01-31';" | tee queryresults.txt

View the query results with the help of cat command.

# cat queryresults.txt

  1. Search for how to use the mysql_config_editor command. It stores the data encrypted.

    You set it up with:

    # mysql_config_editor set --login-path=myserver --user=adam -p

    Then you can do:

    alias sqlcmd='mysql --login-path=myserver  -Dmydbname  --execute'

    And finally:

    sqlcmd 'DESC table'
  2. Maybe we can create a file name ‘.my.cnf’ under user home directory, add mysql user, password in it, like this

    then change its mode as 600, so we can use command ‘mysql’ directly without set parameter ‘-p’, and password prompt would not appear.

  3. Wow , someone should make a tutorial on how to make a READ ONLY user for that tutorial. Even if the password is prompted, newcomers would easily add the root password to a script and pat themselves on the back.
