a typical ls output looks like this...
-rw-r----- 1 ltaber wheel 1876 Mar 28 16:55 tmp
assuming the time stamp is the 8th field and file is 9 th field (check this out)
I don't have UNIX shell with me at present... but try listing with this loop...
----------------------------------------------------------
for lsout in `ls -l`
do
hours=`echo $lsout | cut -d " " -f 8 | cut -d ":" -f 1`
filetodelete=`echo $lsout | cut -d " " -f 9`
if [ $hours -lt 19 -o $hours -ge 20 ]
then
echo $filetodelete
fi
done
----------------------------------------------------------
I hope you got what I'm trying to do...
if the above code lists the files you wanted to delete ( you may need to make some modifications )... you can replace the echo with a "rm -f $filetodelete"
the above scheme will work if none your files are older than 6 months.. because ls -l will not list time stamp if a file is older than 6 months... also I assume that none of your files is having spaces in its name...
wish to see better ways for this...
Cheers!
Vishnu.

certwatch
CERTWATCH(1) Cryptography Utilities CERTWATCH(1)
NAME
certwatch - generate SSL certificate expiry warnings
SYNOPSIS
certwatch [OPTION...] filename
DESCRIPTION
The certwatch program is used to issue warning mail when an SSL certificate is about to expire.
The program has two modes of operation: normal mode and quiet mode. In normal mode, the certificate given by the filename argument is
examined, and a warning email is issued to standard output if the certificate is outside its validity period, or approaching expiry. If the
certificate cannot be found, or any errors occur whilst parsing the certificate, the certificate is ignored and no output is produced. In
quiet mode, no output is given, but the exit status can still be used.
The certificate can be specified by its nickname or by a path to the containing file.
OPTIONS
--quiet, -q
Enable quiet mode; no output is produced whether the certificate is expired or not
--period days, -p days
Specify the number of days within which an expiry warning will be produced; default is 30. Expiry warnings are always produced if, on
the day of invocation, the certificate is not yet valid, has already expired, or is due to expire either that day or the following day.
--address address, -a address
Specify the address used in the To field of the warning e-mail issued if quiet mode is not enabled. The default is root.
--directory cert-directory, -d cert-directory
Specify the database directory containing the certificate and key database files. The default is yet to be determined.
DIAGNOSTICS
The exit code indicates the state of the certificate:
0
The certificate is outside its validity period, or approaching expiry
1
The certificate is inside its validity period, or could not be parsed
NOTES
The certwatch program is run daily by crond from the file /etc/cron.daily/certwatch to generate warning mail concerning the imminent expiry
of SSL certificates configured for use in the Apache HTTP server. These warnings can be disabled by adding the line: NOCERTWATCH=yes to the
file /etc/sysconfig/httpd. Additional options to pass to certwatch can be specified in that file in the CERTWATCH_OPTS environment
variable.
FILES
/etc/cron.daily/certwatch, /etc/sysconfig/httpd
