extract part of hostname in a script
I need to automate something as part of post processing in a script . Each project is identified by a 3 letter string which is part of hostname and based on hostname I need to copy a particular file to that machine from my distribution .

here are hostnames

pprdifeap01.corp.host.net (where ife is the string I need ) and if so I copy /opt/distribution/ife.cfg to /usr/local/jboss/bin

pprdyamap05.corp.host.net ....if "yam" then cp /opt/distribution/yam.cfg /usr/local/jboss/bin

I have around 10 projects or so with different strings with different config files.

thanks

hostname

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.
