Remove the date portion from file name

hi,
I am trying to remove the last field before the period (.) from a list of file names in a directory in a shell script.
Below is the list of file names.

PHP Code:
ENVID_archival_20120214092258.log            
ENVID_Get_Source_Files_20120214091828
.log  
ENVID_Get_Source_Files_20120214092523
.log
ENVID_email_notification_20120214091829
.log  
ENVID_Get_Source_Files_20120214092026
.log 
_ and the date part followed by it have to be removed and the result should be:
PHP Code:
ENVID_archival.log            
ENVID_Get_Source_Files
.log  
ENVID_Get_Source_Files
.log
ENVID_email_notification
.log  
ENVID_Get_Source_Files
.log 
I tried with cut. But as the date field position is dynamic, I could not get it through successfully. can some one help?

thanks

If you open vi specify a path to a file that does not exist, vi will create a new, blank file at that location in the filesystem and open it.

PMDARSYSLOG(1)						       Performance Co-Pilot						    PMDARSYSLOG(1)

NAME
pmdarsyslog - rsyslog (reliable and extended syslog) PMDA DESCRIPTION
pmdarsyslog is a Performance Metrics Domain Agent (PMDA) which exports metric values from the rsyslogd(8) server. Further details about rsyslog can be found at http://www.rsyslog.com/. INSTALLATION
If you want access to the names and values for the rsyslog performance metrics, do the following as root: # cd $PCP_PMDAS_DIR/rsyslog # ./Install If you want to undo the installation, do the following as root: # cd $PCP_PMDAS_DIR/rsyslog # ./Remove pmdarsyslog is launched by pmcd(1) and should never be executed directly. The Install and Remove scripts notify pmcd(1) when the agent is installed or removed. In order to use this agent, rsyslog stats gathering must be enabled. This is done by adding the lines: $ModLoad impstats $PStatsInterval 5 # log every 5 seconds syslog.info |/var/log/pcp/rsyslog/stats to your rsyslog.conf(5) configuration file after installing the PMDA. Take care to ensure the syslog.info messages do not get logged in any other file, as this could unexpectedly fill your filesystem. Syntax useful for this is syslog.!=info for explicitly excluding these. FILES
/var/log/pcp/rsyslog/stats named pipe containing statistics exported from rsyslog, usually created by the PMDA Install script. $PCP_PMDAS_DIR/rsyslog/Install installation script for the pmdarsyslog agent $PCP_PMDAS_DIR/rsyslog/Remove undo installation script for the pmdarsyslog agent $PCP_LOG_DIR/pmcd/rsyslog.log default log file for error messages from pmdarsyslog SEE ALSO
pmcd(1), rsyslog.conf(5), rsyslogd(8). 3.8.10 Performance Co-Pilot PMDARSYSLOG(1)
