cat file and parse output

Hello,

I'm new to shell scripting and did a search on the forum to what I want to do but couldn't find anything.

I have about 9 routers that outputs to 1 syslog file daily named cisco.year.mo.date.log ex: cisco.2009.05.11.log

My goal is to make a parsing script that cats today's syslog file, grep the router's hostname in the file, and output it to a text file with today's date and hostname, and continue to append to that file until the next day. I intend to make this script run every 30 minutes which is something I know how to do via the crontab. If a router doesn't generate a syslog file then skip that hostname. This is so it will be easier for me to see if that router generated a syslog file and what happened to it. Any help or guidance will be greatly appreciated

Thanks in advance

syslog.auth(4)						     Kernel Interfaces Manual						    syslog.auth(4)

NAME
syslog.auth - authorization file for accepting remote syslog messages SYNOPSIS
# format: Each fully qualified host name on a separate line hostname.domain_name DESCRIPTION
The /etc/syslog.auth file specifies which remote hosts are allowed to forward syslog messages to the local host. For the sake of security, only messages coming from remote hosts listed in the local /etc/syslog.auth file will be logged by the syslogd daemon. If the /etc/syslog.auth file does not exist, then messages coming from any host will be accepted. Each remote host name should appear in a separate line in /etc/syslog.auth. A line started with the # character is considered as a comment and is thus ignored. A host name must be a complete domain name such as trout.zk3.dec.com. If a domain host name is given, it must either appear in the local /etc/hosts file or be able to be resolved by the local name server (BIND). Note that a host name can have at most as many characters as defined by the MAXHOSTNAMELEN constant in <sys/param.h>, although each line in the /etc/syslog.auth file can have up to 512 characters. The /etc/syslog.auth file must be owned by root and has a permission of 0600. To invoke a new version of the /etc/syslog.auth file, run the following command (as the super user) to initialize the syslogd daemon: kill -HUP `cat /var/run/syslog.pid` EXAMPLES
The following example provides a typical authorization file: # format: Each fully qualified host name on a separate line c3poid.rvo.dec.com r2d2id.ckt.dec.com FILES
Location of the authorization file. RELATED INFORMATION
Commands: syslogd(8), syslog(1) System Administration delim off syslog.auth(4)
