linux - Apache access log for the most common IP address bash script -

-

so running bash script on apache log file can sort ip addresses , show common on shows @ bottom of page no top how show highest lowest

this script far

cat access_log.txt | awk '{print $1}'| uniq -c |sort -n -k 1| tail

in txt file have 

10.23.234.0 250.40.56.78 8.45.98.250 10.23.234.0 250.40.56.78 8.45.98.250 10.23.234.0 250.40.56.78 10.23.234.0 250.40.56.78 10.23.234.0  10.23.234.0

the output is

2 8.45.98.250 4 250.40.56.78 6 10.23.234.0

i want output 

6 10.23.234.0 4 250.40.56.78 2 8.45.98.250

also want best way print out dns name next example

66.249.73.234 - - [12/fegb/2013:12:00:09 +1100] "get /java/tut/tut.sgml-065.html http/1.1" 200 752 "-" "mozilla/6.0 (compatible; googlebot/2.1; +http://www.google.com.html)"

so be

66.249.73.234 - http://www.google.com.html

thanks

you can use this:

awk '{a[$1]++} end {for (i in a) print a[i],i | "sort -rnk1"}' access_log.txt 5 10.23.234.0 4 250.40.56.78 2 8.45.98.250 1 10.23.234.0

or

awk '{a[$1]++} end {for (i in a) print a[i],i}' access_log.txt | sort -rnk1

r in sort reverse

to html data

awk '{split($0,a,"http|[)]");print $1" - http"a[2]}' file 66.249.73.234 - http://www.google.com/bot.html

top print dns top 2 records.

awk '{split($0,b,"http|[)]");a[$1" - http"b[2]]++} end {for (i in a) print a[i],i}' file | sort -rnk 1 | awk 'nr>2 {$0=$1fs$2} 1'
