counting ip addresses
|
|
| rogv24@yahoo.com 2006-10-27, 1:17 pm |
| I am trying to write a routine to provide counts from a list of IP
addresses that are sorted.
example:
2.3.4.5
2.3.4.5
2.3.4.5
10.20.20.40
10.20.20.40
report would like this 2.3.4.5 - sum 3
10.20.20.40 - sum 2
thanks

I would suggest you take a look at the uniq command,
and especially to its -c flag.

If you don't mind Python:
#!/usr/bin/python
# emulates uniq -c
# *-* encoding: utf-8 -*-
import sys
res = {}
count = 1
for x in open(sys.argv[1], "r").readlines():
try:
res[x] += 1
except:
res[x] = 1
for key, value in res.items():
print "#%i %s occured %i times!"%(count, key.replace("\n", ""), value)
count += 1
res = {}
Or just use uniq and the -c switch!

Is this homework? It's simple in awk.
