喜逢身體 我試圖用「DF -oi」命令

我寫腳本如下因素線

#FS_LIST=`df -o i | grep -v Filesystem | awk '{print $6}' | egrep -v "fd|proc" | tr -d "/"` 
FS_LIST=`df -o i | grep -v Filesystem | grep -v cdrom | awk '{print $6}' | egrep -v "fd|proc" ` 

for FS in $FS_LIST; 
do 
     CAPACITY=`df -o i "/${FS}" | awk '{print $5}' | tail -1 | tr -d %` 
     LIMIT=80 
     DESC="FS=$FS , Capacity=${CAPACITY}% , Limit=${LIMIT}%" 
#  echo $DESC 
     if [ $CAPACITY -gt $LIMIT ] 
     then 
       LOGIC_ID="${HOST}_${FS}_${CAPACITY}_Is_Over_Limit" 
       echo "LOGIC_ID = " $LOGIC_ID 
       #Send_Alarm_Up; 

監控文件的容量shell腳本

和我收到這個筆記

df: operation not applicable for FSType autofs 
df: operation not applicable for FSType ctfs 
df: operation not applicable for FSType devfs 
df: operation not applicable for FSType fd 
df: operation not applicable for FSType hsfs 
df: operation not applicable for FSType mntfs 
df: operation not applicable for FSType nfs 
df: operation not applicable for FSType objfs 
df: operation not applicable for FSType proc 
df: operation not applicable for FSType sharefs 
df: operation not applicable for FSType tmpfs 

我做了什麼錯？

Answer 1

正是這樣說：那些「文件系統」是內核結構，不支持該操作。

你可以不理會通過發送標準錯誤使用2>/dev/null， 並使用邏輯與操作&&到dev空只能做下面的命令時，DF成功執行。

Answer 2

df -o i給你的文件對FS的數量看

Filesystem    iused ifree %iused Mounted on 
/dev/md/dsk/d0  263357 1606147 14% /
/dev/md/dsk/d5   23401 1222935  2% /var
