====== Execute Shell Command ======

Executes a system command. Because this refactoring doesn't generate SQL like most, using LiquiBase commands such as migrateSQL may not work as expected. **Therefore, if at all possible use refactorings that generate SQL.**


===== Sample =====

<code xml>
<executeCommand executable="mysqldump" os="Windows XP">
    <arg value="--add-drop-database"/>
    <arg value="--compress"/>
    <arg value="dbName"/>
</executeCommand>
</code>
