To execute SQL commands through a Linux shell script, you can use the command-line interface of the database management system installed on your machine. Here are the general steps to follow:
1
|
#!/bin/bash
|
1
|
mysql -u <username> -p<password> -h <hostname> -e "<SQL command>" |
1
|
psql -U <username> -h <hostname> -c "<SQL command>" |
1
|
sqlite3 <database_file> "<SQL command>" |
Replace <username>
, <password>
, <hostname>
, and <database_file>
with the appropriate database connection details and specify the required SQL command inside "<SQL command>"
.
1
|
chmod +x execute_sql.sh |
1
|
./execute_sql.sh |
The SQL command specified in the script will be executed using the respective DBMS command-line tool, and the output or results will be displayed on the console/terminal.

This is applicable for MySQL, PostgreSQL, and SQLite databases. In addition to the methods described above, it is also possible to use other CLI tools and third-party libraries to execute SQL commands. For example, you can use the 'sqlite3' command line interface for SQLite databases, 'psql' for PostgreSQL databases, and 'mysql' for MySQL databases. Make sure to install the necessary packages for your desired Database Management System.
Each DBMS tool has its own command-line options and parameters for executing SQL commands. You can refer to the respective documentation for more advanced options and functionalities.
Using this approach, you can automate SQL command execution and integrate it within your Linux shell scripts.
