Expanding everything means re-implementing what the shell does. wordexp() would be ideal for this, except that wordexp() is not portable enough. By the time we end up rewriting enough code to do what wordexp() already could do, we are adding lots of bloat into virsh to make it mimic what /bin/sh can already do. Ergo, I think that this patch idea is not worth it. If a user wants shell expansions, they should let the shell do it, when building up the virsh command line. That is, instead of trying to do expansions in a virsh interactive session: $ virsh virsh# echo $HOME you should just let the shell do it beforehand: $ virsh "echo $HOME"
Thanks for explanation, I get it. -- libvir-list mailing list libvir-list@redhat.com https://www.redhat.com/mailman/listinfo/libvir-list
