如果磁盘空间使用率大于60%就执行某个网页

#bin/bash
#set -x
checkLog=/var/log/check-space.log
fullFlag=0
percent=60
df -h > $checkLog
percent_list=$(cat $checkLog  | awk '{print $5}' | grep -Eo "[0-9]+")
for num in $percent_list
do
    if [ $num -ge $percent ]; then
        fullFlag=1
    fi
done
#echo $percent_list

if [ $fullFlag -eq 1 ]; then
echo "$(hostname): used disk space is more than $percent!"
