#sed -i 's/original/new/g' file.txt

Explanation:

    sed = Stream Editor
    -i = in-place (i.e. save back to the original file)

    The command string:
        s = the substitute command
        original = a regular expression describing the word to replace (or just the word itself)
        new = the text to replace it with
        g = global (i.e. replace all and not just the first occurrence)

    file.txt = the file name

Default my.cnf content of maria-db

 

 # The MariaDB configuration file
#
# The MariaDB/MySQL tools read configuration files in the following order:
# 0. "/etc/mysql/my.cnf" symlinks to this file, reason why all the rest is read.
# 1. "/etc/mysql/mariadb.cnf" (this file) to set global defaults,
# 2. "/etc/mysql/conf.d/*.cnf" to set global options.
# 3. "/etc/mysql/mariadb.conf.d/*.cnf" to set MariaDB-only options.
# 4. "~/.my.cnf" to set user-specific options.
#
# If the same option is defined multiple times, the last one will apply.
#
# One can use all long options that the program supports.
# Run program with --help to get a list of available options and with
# --print-defaults to see which it would actually understand and use.
#
# If you are new to MariaDB, check out https://mariadb.com/kb/en/basic-mariadb-articles/

#
# This group is read both by the client and the server
# use it for options that affect everything
#
[client-server]
# Port or socket location where to connect
# port = 3306
socket = /run/mysqld/mysqld.sock

# Import all .cnf files from configuration directory
!includedir /etc/mysql/conf.d/
!includedir /etc/mysql/mariadb.conf.d/

This generally happens, when innodb_strict_mode is active, 

make it off / deactivate using this command in sql prompt,

 

MariaDB [(none)]> SET GLOBAL innodb_strict_mode = 0;
Query OK, 0 rows affected (0.000 sec)

That's it.
