Running ij scripts

You can run scripts in ij in any of the following ways.

Name an input file as a command-line argument. For example:
```
java org.apache.derby.tools.ij myscript.sql
```
Redirect standard input to come from a file. For example:
```
java org.apache.derby.tools.ij < myscript.sql
```
Use the Run command from the ij command line. For example:
```
ij> run 'myscript.sql';
```

Note: If you name an input file as a command-line argument or if you use the Run command, ij echoes input from a file. If you redirect standard input to come from a file, ij does not echo commands.

You can save output in any of the following ways:

By redirecting output to a file:

java org.apache.derby.tools.ij myscript.sql > myoutput.txt

By setting the ij.outfile property:

java -Dij.outfile=myoutput.txt org.apache.derby.tools.ij 
    myscript.sql

ij exits when you enter the Exit command or, if executing a script, when the end of the command file is reached. When you use the Exit command, ij automatically shuts down an embedded Derby system by issuing a connect jdbc:derby:;shutdown=true request. It does not shut down Derby if it is running in a server framework.
