I have a program i'm working on that basically will automate a virtual machine post install + extending an lvm

i've got the code for the extending all working

now my clone server that will run this program has an ip and FQDN that i need to change

the program usage is as follows:

Usage: ./update-vm -i <IP_ADDRESS> -s <SERVER_NAME>

 -i  [IP_ADDRESS]      IP Address to change to, format: A.B.C.D
 -s  [SERVER_NAME]     Hostname to change to, format: foo.foo.com or f
+oo.foo.foo.foo.com

 -h        Show this text

i was trying to avoid using system or just one liner perl search/replaces for the IP and hostname strings to search for in /etc/ and change

my variables are $old_ip statically set in program, $old_name statically set in program, $new_ip gotten from ARGV and $new_name gotten from ARGV

I did read about Find::File and Find::Glob and File::Slurp but i cant find any really good examples that dont just try and do find or system calls which i would like to avoid for best practice reasons, plus the examples ive seen are calling from a file where im grabbing from user input from my Getops::Long

thanks in advance for your help monks!

if i can provide anymore information ill be happy to!

In reply to need to be able to search/replace by ip and hostname recursively in /etc based off ARG input by globalsec23
