Have a look at the thread http://www.computing.net/unix/wwwboard/forum/5648.html Let Mr Robertson know what fine work he has there.

In general, time calculations in the shell are difficult. Consider using perl for date and time calculations for an OS independent answer. ========================== #!/usr/bin/perl -w use strict; use Time::ParseDate; #Read 2 date strings from stdin print "Enter earliest date: "; my $date1=<STDIN>; print "Enter latest date: "; my $date2=<STDIN>; chomp $date1; chomp $date2; #Convert to seconds since start of epoch my $time1 = parsedate($date1); my $time2 = parsedate($date2); #Compute days difference my $tdiff = $time2 - $time1; my $ddiff = $tdiff/60/60/24; print "Difference is $ddiff days\n"; ======================== # ./date.pl Enter earliest date: Mar 27 2005 05:48:02 Enter latest date: Apr 2 2005 15:31:17 Difference is 6.40503472222222 days

thanx a lot david for quick reply.sorry for mailing you.Before posting on this forum.i was thinking of using perl and had my script but then as told by my specifications.that it may be possible that perl is not installed as package.is there any way i can use date command or may be i can use awk for finding out the diffrence,is there any way.could you suggest me something, abhishek hi my question is abt scripting. i want to find the diffrence in two dates. dates are in /var/log/messages Mar 27 05:48:02 abhargav sshd[1151]: Apr 2 15:31:17 abhargav sshd[1151]: no
