Full Discussion: Subtracting Variables which are commands
Top Forums UNIX for Dummies Questions & Answers Subtracting Variables which are commands Post 1799 by 98_1LE on Friday 30th of March 2001 08:55:06 AM

Using last is the better solution, but there needs to be some logic coded in. The problem is the case where the user has been logged in for more than 24 hours, last gives you something like:

chuckb xdmremote sunws6:0 Tue Mar 27 07:36 - 13:45 (2+06:08)

In this case I have been logged in for more 2 days, 6 hours and 8 minutes.

ds.log(4)							   File Formats 							 ds.log(4)

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
