How to find ip addresses in logfiles?
Hi guys,
I need to check a few log files as below to find out whether certain ip addresses is present on these log files.
type8code0: ls -alt
-rw-r--r-- 1 root other 796219588 Mar 20 02:25 logfile
drwxr-xr-x 2 root root 1536 Mar 20 02:00 .
-rw-r--r-- 1 root other 1854093343 Mar 20 02:00 logfile.hour02
-rw-r--r-- 1 root other 366729263 Mar 20 01:00 logfile.hour01
-rw-r--r-- 1 root other 9001399293 Mar 20 00:47 logfile.20.Z
-rw-r--r-- 1 root other 8267721901 Mar 19 00:45 logfile.19.Z
-rw-r--r-- 1 root other 7498682761 Mar 18 00:39 logfile.18.Z
-rw-r--r-- 1 root other 6196926607 Mar 17 00:31 logfile.17.Z
-rw-r--r-- 1 root other 4794493570 Mar 16 00:23 logfile.16.Z
I've saved the list of ip addresses in “iplist” file.
cat iplist
10.10.10.10
10.10.10.11
10.10.10.12
10.10.10.13
10.10.10.14
What is the best command to do this?
This is what I do now, but it takes sometime. Hopefully there is easy way to do this.
grep 10.10.10.10 logfile > output_logfile_10.10.10.10
grep 10.10.10.11 logfile > output_ logfile_10.10.10.11
and so on
zcat logfile.16.Z | grep 10.10.10.10 > output_logfile.16.Z_10.10.10.10
zcat logfile.16.Z | grep 10.10.10.11 > output_logfile.16.Z_10.10.10.11
and so on
Thanks
