Dynamically create arrays
I have a bash challenge. I have several virtualization hosts for which I need to collect VM information.
I need to dynamically create an array for each host. The contents of the array should be the list VMs running on the host. Here's the logic; I just need someone to help me with the details:
num_hosts=30
for ((n=0; n<num_hosts; n++)); do
declare -a host$nvms
host$nvms=(`comand-to-get-vm-list`)
done
The result should be something like the following:
host0vms=("host0vm1" "host0vm2" "host0vm3")
host1vms=("host1vm1" "host1vm2" ...)
...
host29vms=("host29vm1" "host29vm2" ...)
Can someone help me out with this? I'd appreciate any assistance I get.
