[問題] sshpass大量執行指令

[blackspace98 (~我愛夏天~)]

我有一個list與script如下
list.txt
10.10.1.1,gary,gary@123
10.10.1.2,belle,belle@123
------------------------------------
#! /bin/bash

while IFS="," read ip user user_passwd
do
        ping -c 3 -w 3 $ip > /dev/null 2>&1
        if [ $? != 0 ]; then
                echo $ip down!
        else
                echo $ip UP!
        fi
done < list.txt

可以執行出我要的結果


但是，換成以下的方式
#! /bin/bash

while IFS="," read ip user user_passwd
do
        ping -c 3 -w 3 $ip > /dev/null 2>&1
        if [ $? != 0 ]; then
                echo $ip down!
        else
                echo $ip UP!
                sshpass -p $user_passwd ssh -o StrictHostKeyChecking=no
$user@$ip 'hostname'
        fi
done < list.txt

出來的結果卻是
10.10.1.1 UP!
localhost1

請教各位這有解決方式嗎? 謝謝

推 yvb: (1) while ... read ... 1<&5; do ... ; done 5< list.txt
→ yvb: (2) sshpass ... ssh ... < /dev/null
→ yvb: 兩種方式任選一種應該都行得通.
→ yvb: (1) 的 1<&5 手誤, 應為 0<&5 才對 :P
