I need to collect last 2 days data from /var/log/messages into a separate file (file format: flmessagetimedaymonth). I have collect today's month, date, time information in separate variable. Please help me in this issue (Probably need awk and grep function).

Code:
month=$(date|awk '{print $2}')
day=$(date|awk '{print $3}')
time=$(date|awk '{print $4}')

#nday=$((day-1))

echo $month $day $time

i=2

#for i in 2 1 0



Sample of /var/log/messages
Code:
Apr 12 12:02:35 RH6 kernel: imklog 4.6.2, log source = /proc/kmsg started.
Apr  12 12:02:35 RH6 rsyslogd: [origin software="rsyslogd" swVersion="4.6.2"  x-pid="1261" x-info="http://www.rsyslog.com"] (re)start

The /var/adm/messages in Solaris seem to log more system messages/errors compared to /var/log/messages in Linux. I checked the log level in Linux and they seem OK. Is there any other log file that contains the messages or is it just that Linux doesn't log great many things? (2 Replies)

NAME

       ds.log - Availability Suite data services log file

DESCRIPTION

       The  /var/adm/ds.log file contains the Availability Suite data services command log. The administration commands log activities to the file
       in the format:

	 date time product: message

       Note that when the size of the log file exceeds 10 Mbytes, ds.log is renamed  /var/adm/ds.log.bak  and a new /var/adm/ds.log file  is  cre-
       ated.

       The ds.log fields are:

       date

	   The	date format is mmm nn, where mmm  is  the local three-character abbreviation for the month and nn is the day of the month on which
	   the event occurred.

       time

	   The time of the event, in hh:mm:ss format.

       product

	   A product code that identifies which component of the data services produced the event. The code is separated  from	the  message  that
	   follows by a colon (:) and a space.

       message

	   A  message  that  can extend over  more  than  one  line describing the event that occurred. The second or following lines are not pre-
	   fixed by  the  date, time, and product code strings.

EXAMPLES

       The example below shows sample ds.log file content:

	 Jan 25 05:26:17 ii: iiboot suspend cluster tag <none>
	 Jan 25 05:32:02 ii: iiboot resume cluster tag <none>
	 Jan 25 05:32:04 sv: svboot: resume /dev/vx/rdsk/bigmaster
