사용 된 디스크 공간을 확인하는 bash 스크립트

Question

디스크 공간 백분율이 사용 된 파티션을 확인하고 제한을 초과하면 경고하는 bash 스크립트를 작성했습니다. 그것은 일부 서버에서 작동하지만 여기에 다른

 
#!/bin/bash                                               
source /etc/profile 

# Devices to check                                                                                
devnames=`df | awk '{print $1}'|tail -n +2` 
email="myemail" 
threshold=95 
for devname in $devnames 
do 
    if [[ -z "$devname" ]] || [[ "$devname" = "tmpfs" ]]; then 
     continue 
    fi 
#                                                 
    let p=`df -k $devname | grep -v ^File | awk '{printf ("%i", 100 - $4*100/$2); }'` 
# echo "$devname $p"                                            

    if [ $p -ge $threshold ] 
    then 
    df -h $devname | mail -s "$devname is low on space" $email 
    fi 
done
