How to find out the location of currently used MySQL configuration file in linux

mysqld --help --verbose will find only location of default configuration file. What if you use 2 MySQL instances on the same server? It's not going to help.

Good article about figuring it out:

"How to find MySQL configuration file?"

You can use the report process status ps command:

ps ax | grep '[m]ysqld'

you can find it by running the following command

mysql --help

it will give you the mysql installed directory and all commands for mysql.
