GlassFish rotate-log

GlassFish has a command to rotate or reset server.log file:

$GLASSFISH_HOME/bin/asadmin rotate-log
After running this command the logs directory looks like this:
/glassfish-3.1/glassfish/domains/domain1/logs > ll
total 200
-rw-r--r-- 1 root 0 Jun 25 10:11 server.log
-rw-r--r-- 1 root 10780 Jun 25 10:11 server.log_2010-06-25T10-09-48
-rw-r--r-- 1 root 16384 Jun 25 10:10 jvm.log
drwxr-xr-x 3 root 102 Jun 25 10:02 server/
This command renames server.log file to a timestamped backup file, and leaves the current server.log file empty. I usually run this command before starting a test run to make sure the current server.log only contains logs from this test run.

For convenience, I also have an alias for it (in tcsh syntax):
alias rlog '$GLASSFISH_HOME/bin/asadmin rotate-log'
