How to stop govc to print out command output

[yjiabj123]

Hi team, I'm using this command line "VALUE=$(govc cluster.usage -json Cluster-$i | jq -r .CPU.Summary.Used)" to assign the cluster cpu value to VALUE. But when there is no valid cluster, it will automatically dump a message "govc: cluster 'Cluster-2' not found" to the shell even if I don't echo the VALUE. How can I stop it from dumping this message to the shell? Thanks!

I'm using this command line "VALUE=$(govc cluster.usage -json Cluster-$i | jq -r .CPU.Summary.Used)" to assign the cluster cpu value to VALUE.

If the message is being sent to stderr this is one approach:

VALUE=$(govc cluster.usage -json Cluster-$i 2>/dev/null | jq -r .CPU.Summary.Used)

The tool may have an option to disable logging output. I'm not as familiar with govc, but you should be able to use the help flag to view supported logging flags.

It works! Thank you so much! :)
