If you're pulling these files from multiple hosts, you might want to add the hostname to the filename or in the file itself.
Yep, the 'hostname' has same value as the 'filename' in my case so that does not really matter I think.

I'm still learning Linux ans I was expecting a one liner command. Apparently I need to learn more about script/bash scripting based on your reply.
I'll do more reading and practicing on awk and bash script.
Thanks Scott!

HOSTNAME(5)							   /etc/hostname						       HOSTNAME(5)

NAME
hostname - Local host name configuration file SYNOPSIS
/etc/hostname DESCRIPTION
The /etc/hostname file configures the name of the local system that is set during boot, with the sethostname(2) system call. It should contain a single newline-terminated host name string. The host name may be a free-form string up to 64 characters in length, however it is recommended that it consists only of 7bit ASCII lower-case characters and no spaces or dots, and limits itself to the format allowed for DNS domain name labels, even though this is not a strict requirement. Depending on the operating system other configuration files might be checked for configuration of the host name as well, however only as fallback. HISTORY
The simple configuration file format of /etc/hostname originates from Debian GNU/Linux. SEE ALSO
