MariaDB starting with 10.5.2
From MariaDB 10.5.2,
mariadb-find-rows is the name of the binary, with
mysql_find_rows a symlink .
mysql_find_rows reads files containing SQL statements and extracts statements that match a given regular expression or that contain USE db_name or SET statements. The utility was written for use with update log files (as used prior to MySQL 5.0) and as such expects statements to be terminated with semicolon (;) characters. It may be useful with other files that contain SQL statements as long as statements are terminated with semicolons.
mysql_find_rows [options] [file_name ...]
Each file_name argument should be the name of file containing SQL statements. If no file names are given, mysql_find_rows reads the standard input.
mysql_find_rows supports the following options:
|Display help and exit.|
|Display queries that match the pattern.|
|Quit after displaying N queries.|
|Do not include USE db_name statements in the output.|
|Start output from this row (first row is 1).|
