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 ":" ??

    There's nothing special about : in a filename (except that Windows FAT filesystem doesn't allow that character) Commented Jul 5, 2013 at 11:45

Not sure if I understand your question right, but in Bash this could work:

for n in {22..99} ; do cp "ifcfg-eth1:$n" "ifcfg-eth1:1$n"; done

That would copy ifcfg-eth1:22 through ifcfg-eth1:99 to ifcfg-eth1:122 through ifcfg-eth1:199.

I'm not sure why you would use such files. If this is about ethX:Y aliases, you no longer need them. You can just ip addr add to the main interface. So maybe you should take a step back and ask a question about the problem you're actually trying to solve.

  • Thanks, this helped! And I will consider your recommendation about "ip addr add"

  • Thanks for the tip as well regarding the ip addr add I wasn't aware of this change either.

It should be as simple as mv "ifcfg-eth1:xx" "ifcfg-eth1:yy"
