How to Automate MySQL Data Restoration from Shell Scripts?

Executing MySQL Commands from Shell Scripts for Automated Data Restoration

Executing SQL commands from shell scripts enables automation and seamless integration of database operations. In this context, you seek to restore data from a SQL file using a shell script.

The command you mentioned utilizes the following syntax:

mysql -h "server-name" -u root "password" "database-name" < "filename.sql"

However, to execute this command successfully from a shell script, you need to modify the format slightly. The critical point is to omit the space between the -p flag and the password.

mysql -h "server-name" -u root "-pXXXXXXXX" "database-name" < "filename.sql"

By eliminating the space, the password is passed directly without prompting for interactive input. For enhanced security, you can store the user and password credentials in ~/.my.cnf to avoid exposing them on the command line.

[client]
user = root
password = XXXXXXXX

With the credentials stored in ~/.my.cnf, you can simplify the command to:

mysql -h "server-name" "database-name" < "filename.sql"

To troubleshoot any issues with your shell script, consider using the -x flag during execution:

bash -x myscript.sh

This will trace the script's execution and help identify potential errors.
