You could just do a grep on a special date and write it to a file which you then check with the little awk line. Not sure if this should be a returning automated mechanism as report for some people that demand it or if it is just for you occasionally.
It can also be included into the awk so grep would not be needed. When I have time again I check it out if nobody comes first Smilie Smilie

Thanks for the feedback,

An automated solution would be the ideal, the files are too big and will be stored in archive. Od course in case of searching a specific range date date, the awk would suit just fine.

awk '$0>=from&&$0<=to' from="2007/03/20 15:13" to="2007/08/19 14:31" log.dates

As for occasional reports, i think that excel pivot tables give an excelent result for visualization

Defining a pattern range - this has nothing to do with arithmetics or something, just a pattern/string/text matching a range (to keep in mind!):

$> cat infile
16-SEP-2009 09:11:47
16-SEP-2009 09:11:47
30-SEP-2009 10:11:47
1-OCT-2009 10:11:47
6-OCT-2009 10:11:47
6-OCT-2009 12:31:01
16-OCT-2009 11:11:47
17-OCT-2009 11:11:47
18-OCT-2009 11:11:47
$> awk 'NR==FNR && $1 ~ /30-SEP-2009/,/16-OCT-2009/ {a[$3]+=1; next} END{for(x in a){print x,"->",a[x]}}' infile -> 2 -> 3

The range is telling awk to take all from the 1st pattern up to the 1st match of the 2nd pattern. So if there are more entries for 16-OCT-2009 you'd better thake 17-OCT, if there is any entries for it. Or maybe just take a complete month to be sure without a range. Instead of a range there could stand a pattern matching for a day, month etc.
Play arround with awk pattern matching Smilie

Thanks! I changed the pattern to a time range like and got a strange output :

awk 'NR==FNR && $2 ~ /15:44:13/,/15:44:14/ {a[$3]+=1; next} END{for(x in a){print x,"->",a[x]}}' access1.log

 -> 2.4.24
 -> 1.4.17
 -> 1.4.8

The counting is done, but part of the ip vanished! Smilie

Hi again,

Is it possible to put this in a perl script or a shell unix script? This is powerfull, but it only works changing the ranges each time. Automation of the process would indeed optimize work! Having a file that could be run from the console, and according to its granularity, split the file and data into severel intervals and sub-files of 1 hour, or split the file and data into subfiles of days, or if bigger splitting into weeks. I look foward from hearing your advice...

So far, you can just take this line and put it in a file called for example, change it's permissions with chown +x and fire it off with ./

Sure, this can be done in perl too. But that's a job for someone else Smilie

Dear All,

I have this code that gives me a list and a count of duplicates in the range specified.
Is there a way of creating a generic pattern for hours/days? Can this range be fixed for a huge file with lots of days?

 awk ' NR==FNR && $2 ~ /06:00:00/,/15:44:14/{print "---"$1"---" $2"---" $3  } {a[$3]+=1; next }END{for(x in a){print" # Ocurrences --->",  x,"--->",a[x]  }}'

---------- Post updated at 07:14 AM ---------- Previous update was at 06:43 AM ----------

So when it "recieves" one bigger file of a week time frame, it would generate several files, named based on the day...f.e. 10-OCT-2009.file, 11-OCT-2009.file and so on....
