It could be done more elegantly, and maybe more efficiently, if you post more details/requirements. This should work for a quick'n'dirty script, though.
Thanks LivinFree for the bash script. I’m new in a bash script, but I’ll try to learn this.
There are a few log files I need to check. All of them located in /logs folder and there are (from March 16 till today):

Code:
# pwd
  /logs

Code:
-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

Code:
# cat iplist
10.10.10.10
10.10.10.11
10.10.10.12
10.10.10.13
10.10.10.14

I would like to send output of this file into my home directory which is in ~/result

Thanks again for your help

I've modified the bash script based on log files location. Do you think this will work? Thanks

Code:
#! /bin/bash

logfile=/logs/logfile.20.Z
logfile=/logs/logfile.19.Z
logfile=/logs/logfile.18.Z
logfile=/logs/logfile.17.Z
logfile=/logs/logfile.16.Z

while read ip; do
    zgrep "$ip" $logfile > ~/acs/output_logfile_${ip}
done <iplist

cachefslog(1M)															    cachefslog(1M)

NAME
cachefslog - Cache File System logging SYNOPSIS
logfile| cachefs_mount_point DESCRIPTION
The command is used to enable or disable logging for a cachefs_mount_point. When the command is used without any options, it displays the logfile. The logfile contains information on the operation performed on a cachefs_mount_point and statistics used by to get the working set size of cache directory. The specified logfile will contain information for all the CacheFS mount points using the same cache direc- tory. A logfile and a cache directory have a 1-to-1 mapping; that is, even if a cache directory is removed and recreated with the same name, the logfile used in the previous instance of the cache directory cannot be reused with the new cache directory. Enabling logging may have performance impact, even if minimal, on the operations for all the CacheFS mount points using the same cache directory. The command is mainly used for debugging purposes. Options The following options are supported. You must be a superuser to use the and options. Specify the logfile to be used. Halt logging. Operands cachefs_mount_point A mount point of a cache file system. RETURN VALUE
returns the following values: Success. non-zero An error occurred. EXAMPLES
1. Checking the logging of a directory. This example checks if the CacheFS file system is being logged: 2. Changing the logfile. This example changes the logfile of to 3. Verifying the change of a logfile. This example verifies the change of the previous example: 4. Halting the logging of a directory. This example halts logging for the directory: AUTHOR
