grep dates on snmp collected data

Seun Ewulomi_1 — Mon, 08 Dec 2003 13:17:21 GMT

Hi people,

I use egrep to grep on data of the format below

10/11/2003 00:00 299 0.43 0.45 140.54 68.34 72.2 32
11/11/2003 00:05 301 0.25 0.34 93.56 39.77 53.78 28
12/11/2003 00:10 300 0.34 0.37 113.91 54.08 59.83 32

1) To see all data for just a certain day I usually do
grep '^10/.*/2003'

2)to see all data for some days I usually do
egrep -e '11/.*/2003' -e '12/.*/2003' snmp.log

Now if I want to see the all data for example from 10/11/2003 - 15/11/2003 how would this be done with awk, egrep or sed.

My main aim is to see/filter all data in a snmp log file just for mondays-fridays and omitting all the weekend dates.

Any help or advice will be grately appreciated.

regards,
seun

If the DAY is always the first column then you can simply do.

grep '^1[1-5]/.*/2003'

Or you can script it with a read statement and input the days you want to grep for... based upon your entry, assigned to a variable.

if i have time i can post a solution like that later.

Have you considered using perl? It has date modules available where you could get the day of the week.

use Date::Calc;
$lower = Date_to_Days(2003,11,10);
$upper = Date_to_Days(2003,11,15);
open(INP,"while() {
chomp;
($mydate)=split(" ",$_);
($day,$mth,$yr)=Decode_Date_EU($mydate);
$date = Date_to_Days($year,$month,$day);
$dow=day_of_week($yr,$mth,$day)
next if $dow >= 6; # skip SAT,SUN
next if $date < $lower || $date > $upper;
print $_,"\n";
}

Hi,

her is my solution.

greetings,

Michael

#!/bin/ksh
while read LINE
do
DATE=`echo ${LINE} | cut -c 1-10`
DOW=`./timeconv "${LINE}" "%d/%m/%Y"|awk '{printf("%s"),$7}'`
if ([[ ${DOW} -gt 0 && ${DOW} -lt 6 ]])
then
echo ${LINE}
fi
done < logfile

timeconv.c
#include
#include
main(argc,arg)
int argc;
char **arg;
{
struct tm t;
if (argc!=3)
{
printf("Usage: arg[0] date datefmt(see man strptime)\n");
return(2);
};
strptime(arg[1],arg[2], &t);
printf("%2d %2d %2d %2d %2d %1d %3d %1d",t.tm_sec,t.tm_min,t.tm_hour,t.tm_mday
,t.tm_mon,t.tm_year,t.tm_wday,t.tm_yday,t.tm_isdst);
}
