以下脚本未按预期工作。我执行它时，Zenity GUI窗口根本没有弹出。我无法找出我犯错误的地方。
相同的脚本在RedHat中显示Zenity结果。
export XAUTHORITY=/home/local/$primaryuser/.Xauthority

usage=$(echo $output | awk '{ print $2}' | cut -d'%' -f1)
filesystem=$(echo $output | awk '{print $3}')
if [ $usage -gt $ALERT ]
then

$filesystem usage is $usage% .Please find the below details to identify which files are utilizing high diskspace and take necessary actions.
