===== Introduction =====
While following a guide the other day, one of the entries in the ifcfg-xxx config file was relating to a UUID for a network interface.
\\ 
  UUID=30892bab-fe54-4c77-9a95-8af5d77ddbd4
\\ 
Unfortunately I did not have this line in my configuration file and needed to add it, but how do I get the UUID? Luckily it is very simple.

==== Find UUID ====
We can use the following command line:
\\ 
  nmcli connection show eno1 |grep connection.uuid
  
  replace 'eno1' with the name of your interface.
\\ 
You will get an output similar to 
\\ 
  connection.uuid:                        30892bab-fe54-4c77-9a95-8af5d77ddbd4
\\ 
The command<color #ed1c24>nmcli connection show eno1</color> on its own will show you quite a lot of information about that interface, but if you only want the UUID then using <color #ed1c24>|grep connection.uuid</color> will display just that.
