以下是nova命令输出中的实例名称列表。

SUBDOMAIN=vms22update
nova list | grep "\-instance-$SUBDOMAIN"
gunicon-instance-vms22updateconfar
haproxy-instance-vms22updateconfar
nsoshim-instance-vms22updateconfar
gunicon-instance-vms22update
haproxy-instance-vms22update
nsoshim-instance-vms22update
我希望看到实例仅以vms22update结束
我试过nova list | grep＆＃34; -instance - ^ $ SUBDOMAIN $＆＃34; 它没有列出任何东西。

你可以试试这个：
TABLEnova list | awk -F"|" '{print $3}' | sed 's/ *$//' | grep -E "vms22update\$"
