MySQL: How to export the output for a non SQL query sentence?

In MySQL 8 server community to export a SQL query's output is possible execute in the MySQL Shell the following command (as most basic):

SELECT * FROM cientifico INTO OUTFILE '/var/lib/mysql-files/cientifico-data.txt';

And it works as expected But for a non SQL query as follows:

SHOW PROCESSLIST INTO OUTFILE '/var/lib/mysql-files/processlist.txt';

Throws the following error > ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'INTO OUTFILE '/var/lib/mysql-files/processlist.txt'' at line 1 Same as:

SHOW DATABASES INTO OUTFILE '/var/lib/mysql-files/databases.txt';

Giving > ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'INTO OUTFILE '/var/lib/mysql-files/databases.txt'' at line 1 Therefore if is possible **Question** * How to export the output for a non SQL query sentence? I am assuming that the INTO OUTFILE syntax is only for SQL sentences, but for non SQL sentences?
