how to grep the contents of a variable..
Hello All,


I've written a script to collect all audit logs files; now i want to see only the files from it which contains certain x tablenames. I've stored all the tablenames in a log file and using it through variable in a script (ex:below)

Code:
$ more tablenames.log (this is just a samle tables there are more than 500 tables to search)
HRC1002
HRC1206
HRC1212
HRS1000
HRS1002
HRS1200
HRS1201

In a script:

Code:
TABLENAMES=/tmp/tablenames.log
SOURCE_FILES=/tmp/sys_audit_files.tmp
 
ls -1tr ${ORACLE_HOME}/rdbms/audit/*.aud > ${SOURCE_FILES}
(which collects more than 200 audit log files; and now i want to use a grep statment in a below for loop to search the tablenames.log file)
 
for i in `cat ${SOURCE_FILES}` ; do
    cat $i |  grep ?????? >> $LOGFILE
done

How do we use a variable or a logfile to grep

thanks in advance..

audit

AUDIT(8)						    BSD System Manager's Manual 						  AUDIT(8)

NAME

     audit -- audit management utility

SYNOPSIS

     audit -e | -i | -n | -s | -t

DESCRIPTION

     The audit utility controls the state of the audit system.	One of the following flags is required as an argument to audit:

     -e      Forces the audit system to immediately remove audit log files that meet the expiration criteria specified in the audit control file
	     without doing a log rotation.

     -i      Initializes and starts auditing.  This option is currently for Mac OS X only and requires auditd(8) to be configured to run under
	     launchd(8).

     -n      Forces the audit system to close the existing audit log file and rotate to a new log file in a location specified in the audit con-
	     trol file.  Also, audit log files that meet the expiration criteria specified in the audit control file will be removed.

     -s      Specifies that the audit system should [re]synchronize its configuration from the audit control file.  A new log file will be cre-
	     ated.

     -t      Specifies that the audit system should terminate.	Log files are closed and renamed to indicate the time of the shutdown.

NOTES

     The auditd(8) daemon must already be running.  Optionally, it can be configured to be started on-demand by launchd(8) (Mac OS X only).  The
     audit utility requires audit administrator privileges for successful operation.

FILES

     /etc/security/audit_control  Audit policy file used to configure the auditing system.

SEE ALSO

     audit(4), audit_control(5), auditd(8), launchd(8)

HISTORY

     The OpenBSM implementation was created by McAfee Research, the security division of McAfee Inc., under contract to Apple Computer Inc. in
     2004.  It was subsequently adopted by the TrustedBSD Project as the foundation for the OpenBSM distribution.
