I need to copy and rename (and then edit) a group of files in the /etc/sysconfig/network-scripts folder. The files are ifcfg-eth1:*

I have ifcfg-eth1 through ifcfg-eth1:121 but need to extend with more addresses, so I want to copy e.g ifcfg-eth1:22 and ifcfg-eth1:23 into ifcfg-eth1:122 and ifcfg-eth1:123 and then edit the copy.

I know how to edit, but not how to copy and rename. Found a lot of renaming info on this site, but I think I don't get the : part right...

How do I handle filenames including ":" ??
