virsh destroy &> /dev/null 仍然顯示空白 output

Question

所以我有一個煩人的問題。 我有一個腳本可以更改給定文本文件的某些配置。 要更改該特定文件，我必須首先銷毀我的 KVM 上的虛擬機來賓。 問題是每次停止時，腳本的 output 中都會有一個空格，如您所見：

vfp-8vr Found!
Check if vfp-8vr has stopped ................................. [OK]

Check if vfp-8vr node has changed ............................ [OK]
Check if vfp-8vr has started ................................. [OK]
vfp-9vr Found!
Check if vfp-9vr has stopped ................................. [OK]

Check if vfp-9vr node has changed ............................ [OK]
Check if vfp-9vr has started ................................. [OK]
vfp-10vr Found!
Check if vfp-10vr has stopped ................................. [OK]

Check if vfp-10vr node has changed ............................ [OK]
Check if vfp-10vr has started ................................. [OK]

我已將 /dev/null 包含到我的腳本中，因為它隱藏了 output，理論上它可以工作，但無論如何都會出現銀行空間......

for i in "${arr[@]}"
do
  if [[ -n "$i" ]]
     then
         echo "$i Found!"

         virsh destroy $i &> /dev/null
         echo -e "Check if \e[32m$i\e[0m has stopped ................................. [OK]"

         virsh numatune $i $opt_node0
         echo -e "Check if \e[32m$i\e[0m node has changed ............................ [OK]"

         virsh start $i &> /dev/null
         echo -e "Check if \e[32m$i\e[0m has started ................................. [OK]"

  fi
done

有誰知道如何在后台運行virsh destroy而不在 output 中顯示煩人的空間？

免責聲明：我已經使用了[Command] > /dev/null 2>&1 & ，同樣的事情：/

傻我，我忘了添加 /dev/null 到 virsh numatune 命令：

Check if vfp-8vr has stopped ................................. [OK]
Check if vfp-8vr node has changed ............................ [OK]
Check if vfp-8vr has started ................................. [OK]
vfp-9vr Found!
Check if vfp-9vr has stopped ................................. [OK]
Check if vfp-9vr node has changed ............................ [OK]
Check if vfp-9vr has started ................................. [OK]
vfp-10vr Found!
Check if vfp-10vr has stopped ................................. [OK]
Check if vfp-10vr node has changed ............................ [OK]
Check if vfp-10vr has started ................................. [OK]
