Question

如何获得输出＆＃34; echo＆＃34;和＆＃34; macaddress＆＃34;在一条线上？这就是我所拥有的：

ipRange="192.168.0."
macaddress= arp  | grep -w  "$ipRange$1" | awk '{print $3,$1}' 

ping -c1 "$ipRange$1" > /dev/null
         if [ $? -eq 0 ]; then
echo  "deze host met mac address en ip address is up $macaddress"
else 
echo "het is down"
fi

这是输出：

VirtualBox ~ $ bash test2.sh 149
e0:b9:a5:f8:24:c3 192.168.0.149
deze host met mac address en ip address is up

Answer 1

这应该以单行输出

ipRange="192.168.0."
macaddress=$(arp  | grep -w  "$ipRange$1" | awk '{print $3,$1}')

ping -c1 "$ipRange$1" > /dev/null
         if [ $? -eq 0 ]; then
echo  "deze host met mac address en ip address is up $macaddress"
else 
echo "het is down"
fi

Answer 2

只需替换macaddress= arp | grep -w "$ipRange$1" | awk '{print $3,$1}'

即可

macaddress=$(arp | grep -w "$ipRange$1" | awk '{print $3,$1}')

如何在一行上放置echo语句和arp语句的输出？
