LOG(9) BSD Kernel Developer's Manual LOG(9)NAME
log -- log a message from the kernel through the /dev/klog device
SYNOPSIS
#include <sys/syslog.h>
void
log(int level, const char *format, ...);
DESCRIPTION
The log() function allows the kernel to send messages to user processes listening on /dev/klog. Usually syslogd(8) monitors /dev/klog for
these messages and writes them to a log file.
All messages are logged using facility LOG_KERN. See syslog(3) for a listing of log levels.

logger - add entries to the system log
SYNOPSIS
/usr/ucb/logger [-f filename] [-i] [-p priority] [-t tag] mm [message]...
DESCRIPTION
The logger utility provides a method for adding one-line entries to the system log file from the command line. One or more message argu-
ments can be given on the command line, in which case each is logged immediately. If message is unspecified, either the file indicated with
-f or the standard input is added to the log. Otherwise, a filename can be specified, in which case each line in the file is logged. If
neither is specified, logger reads and logs messages on a line-by-line basis from the standard input.
OPTIONS
The following options are supported:
-i Log the process ID of the logger process with each line.
-f filename Use the contents of filename as the message to log.
-p priority Enter the message with the specified priority. The message priority can be specified numerically, or as a facility.level
pair. For example, `-p local3.info' assigns the message priority to the info level in the local3 facility. The default pri-
ority is user.notice.
-t tag Mark each line added to the log with the specified tag.
EXAMPLES
Example 1: Logging a message
The command:
example% logger System rebooted
will log the message `System rebooted' to the facility at priority notice to be treated by syslogd as other messages to the facility notice
are.
Example 2: Logging messages from a file
The command:
example% logger -p local0.notice -t HOSTIDM -f /dev/idmc
will read from the file /dev/idmc and will log each line in that file as a message with the tag `HOSTIDM' at priority notice to be treated
by syslogd as other messages to the facility local0 are.

Can someone suggest on this script :
let's say the logs files are available for Jan 07, Dec 06, Nov 06, Oct 06
the script should identify the latest months logs, i.e Jan 07
it should then delete anything older than 2 months, which will be logs for Nov 06 & Oct 06. (40 Replies)
Hey Guys,
I am trying to grep within a file to find and output certain parts of lines to other file(s). The output files need to have a dynamic file name based on a field in the main log.
The problem is that every line of the log is not the same, and often not even similar.
