Sort IP addresses for a bash program

xbaez · 04-29-2010, 11:09 AM

Hello
I have for example the following IP addresses:

24.172.220.218
41.239.36.19
63.215.202.234
66.176.124.22
78.110.50.139
79.143.179.98
83.4.136.214
84.111.37.26
163.24.136.10
187.40.64.252
187.41.94.232
24.172.220.218
187.45.225.192
189.10.91.21
190.77.158.128
193.34.144.193

How can I sort those IP addresses?
I want to sort them using the first 3 numbers

I also want to count the number of times that address is repeated

This is a batch program

Thanks a lot

sort

sort -n should do it for you, and there is options within grep to count the number of times something appears (I believe its grep at least).

so

Code:

cat list of ips | sort -n > list_of_sorted_ips
grep list_of_sorted_ips (some option for count)

There is - grep -c <pattern> - but this counts the number of times <pattern> appears (meaning that you'd have to repeat it for each IP address.

The command you want is uniq -c

Code:

[rh@mypc ~]$ cat ip_list | sort -n | uniq -c
      2 24.172.220.218
      1 41.239.36.19
      1 63.215.202.234
      1 66.176.124.22
      1 78.110.50.139
      1 79.143.179.98
      1 83.4.136.214
      1 84.111.37.26
      1 163.24.136.10
      1 187.40.64.252
      1 187.41.94.232
      1 187.45.225.192
      1 189.10.91.21
      1 190.77.158.128
      1 193.34.144.193
