My current directory does not exist?

Just trying to get going with lb using the quickstart tutorial - I put together this script


java -jar  ~/liquibase-2.0.2-bin/liquibase.jar --driver=oracle.jdbc.OracleDriver </div>

     --classpath=$CLASSPATH:/usr/local/oracle/product/10.2.4/client/instantclient/ojdbc14.jar </div>

     --changeLogFile=changelog.xml </div>

     --url=“jdbc:oracle:thin://myhost:1521:dbmigrate” </div>

     --username=dbmigrate </div>

     --password=password </div>


Which responds with 

tgreen@mactgreen ~/liquibase-quick-test $ ./ 

Liquibase Update Failed: /Users/tgreen/liquibase-quick-test does not exist

SEVERE 10/26/11 6:22 PM:liquibase: /Users/tgreen/liquibase-quick-test does not exist

liquibase.exception.CommandLineParsingException: /Users/tgreen/liquibase-quick-test does not exist

at liquibase.integration.commandline.Main.main(

ie telling me that my current directory does not exist.  What does this mean?

What do you have in $CLASSPATH ? Is ~ /Users/tgreen on your machine?
