"sed" to check file size & echo " " to destination file
Hi,
I've modified the syslogd source to include a thread that will keep track of a timer(or a timer thread). My intention is to check the file size of /var/log/messages in every one minute & if the size is more than 128KB, do a echo " " > /var/log/messages, so that the file size will be set back to zero.
If somebody can help me with a sed command to check the size of messages & to do a echo "" > messages ,if the size is greater than 128KB, I'll really grateful.
Wishes
Jay

syslog.conf
syslog.conf(4) Kernel Interfaces Manual syslog.conf(4)
NAME
syslog.conf - syslogd configuration file
SYNOPSIS
facility.severity destination Where: Is part of the system generating the message, specified in /usr/include/sys/syslog_pri.h.
See also the syslogd(8) reference page. The severity level, which can be emerg, alert, crit, err, warning, notice, info, or debug. See
/usr/include/sys/syslog_pri.h.
The syslogd daemon logs all messages of the specified severity level plus all messages of greater severity. For example, if you
specify level err, all messages of levels err, crit, alert, and emerg or panic are logged. A local file pathname to a log file, a
host name for remote logging or a list of users. In the latter case the users will receive messages when they are logged in. An
asterisk (*) causes a message to be sent to all users who are currently logged in.
DESCRIPTION
The /etc/syslog.conf file is a system file that enables you to configure or filter events that are to be logged by syslogd. You can specify
more than one facility and its severity level by separating them with semicolons.
You can specify more than one facility logs to the same file by separating the facilities with commas, as shown in the EXAMPLES section.
The syslogd daemon ignores blank lines and lines that begin with an octothorpe (#). You can specify # as the first character in a line to
include comments in the file or to disable an entry. The facility and severity level are separated from the destination by one or more tab
characters.
If you want the syslogd daemon to use a configuration file other than the default, you must specify the file name with the following com-
mand: # syslogd -f config_file
Daily Log Files
You can specify in the /etc/syslog.conf file that the syslogd daemon create daily log files. To create daily log files, use the following
syntax to specify the path name of the message destination: /var/adm/syslog.dated/ { file} The file variable specifies the name of the log
file, for example, mail.log or kern.log. If you specify a /var/adm/syslog.dated/file path name destination, each day the syslogd daemon
creates a sub-directory under the /var/adm/syslog.dated directory and a log file in the sub-directory, using the following syntax:
/var/adm/syslog.dated/ date / file Where: The date variable specifies the day, month, and time that the log file was created. The file
variable specifies the name of the log file you previously specified in the /etc/syslog.conf file. The syslogd daemon automatically cre-
ates a new date directory every 24 hours and also when you boot the system. The current directory is a link to the latest date directory.
To get the latest logs, you only need to reference the /var/adm/syslog.dated/current directory.
EXAMPLES
The following is a sample /etc/syslog.conf file: # # syslogd config file # # facilities: kern user mail daemon auth syslog lpr binary #
priorities: emerg alert crit err warning notice info debug # kern.debug /var/adm/syslog.dated/kern.log user.debug /var/adm/sys-
log.dated/user.log daemon.debug /var/adm/syslog.dated/daemon.log auth.crit;syslog.debug /var/adm/syslog.dated/syslog.log mail,lpr.debug
/var/adm/syslog.dated/misc.log msgbuf.err /var/adm/crash.dated/msgbuf.savecore kern.debug /var/adm/messages kern.debug /dev/console *.emerg
