Calling shell script from java program and passing arguments to a shell script from java for loop

Question

Does anyone know if it is possible to call a shell script from within Java program and also pass an argument to that shell script from the for loop of that java class? In my shell script I am setting MySQL system variables to different values to see if those values affect the performance of the database application. I could have set those values through JDBC, but as I am working with MySQL, it is not possible to restart the database from JDBC, after each query execution.

Yes it is possible. For something like this you would probably be better off just using a batch file or something to do it though.

If you really do need to use java try:

Runtime.exec() is what you are looking for.

Runtime.getRuntime().exec("theScript.sh param1 param2);

..modulo exception handling.

You may want to look into Apache Commons
