Help on Loops to Grep logs

Hi,

Thanks RudiC for bringing up the order of the timestamp. Yes it does matter. Please help.

Current Setup:
Logs were rotated every 4hrs and they were compressed. If the logs exceed 10gb, it will be compressed (.Z), if not script will just zipped the logs (.gz). So archive directory may sometime contains *.gz and *.Z files, and there are times that it only contains *.gz files



Goal:
Help on Loops to Grep logs per domain, in a single text file, regardless if logs are in *gz or *Z.

domainlist="4prd 5prd 6prd 7prd 8prd"

expected output will be:

4prd_host.txt
5prd_host.txt
6prd_host.txt
7prd_host.txt
8prd_host.txt


I try to create one, but having problem on if statement.
Code:
domainlist="4prd 5prd 6prd 7prd 8prd"
for domain in $domainlist
   do
           if [ ? ] ; then
                gzgrep "$domain" $dir_arch/logs/*gz >> $dir_arch/logs/$domain_$myhost.txt    << for zip files (e.q log.gz)
                 gzip -f $dir_arch/logs/$domain_$myhost.txt
  else
                zcat $dir_arch/logs/*Z | grep "$domain" >> $dir_arch/logs/$domain_$myhost.txt << for compress files(e.q log.Z)
                gzip -f $dir_arch/logs/$domain_$myhost.txt
           fi
done

Kindly help. Thanks!

Regards,
Choco

NAME
clfdomainsplit - split Common-Log Format web logs based on domain name SYNOPSIS
clfdomainsplit [--help] [-i input] [-d defaultfile] [-c cfg-file] [-o directory] DESCRIPTION
The clfdomainsplit program will split up large CLF format web logs based on domain name. This is for creating separate log analysis passes for each domain hosted on your server. OVERVIEW
The input parameter specifies the file to read (default is standard input). The defaultfile parameter specifies where data goes if it doesn't have a domain (either it has an IP address for the server or it doesn't have the server-name - the URL is relative to the root of the web server only). The default will be to print them on standard error. The cfg-file parameter is for specifying the rules for determining what is a different domain name. For example www.coker.com.au belongs in the same file as coker.com.au and abc.coker.com.au because domain names ending in .au have three major components. The domain names www.workbenelux.nl and workbenelux.nl belong in the same file because domain names ending in .nl have two major components (as do .com, and .gov), wheras anything ending in .va belongs to the same organization. The rules are of the form number:pattern which lists the number of domain parts which are significant (2 for .com and for a simple string comparison, the default will be: 2:com 2:nl 3:au 3:uk If no config file is specified then it will look for /etc/clfdomainsplit.cfg. Of course comments start with #. Also note that the first match will be used! The directory parameter is to specify the location for the files to be created (default is the current directory). I recommend that you use a directory for this and nothing else as you never know how many files may be created! EXIT STATUS
