我想做一個script,當行 <cat /proc/net/arp>  'HW address' show <incomplete>, 之後行<sudo ifconfig eth0 down> and <sudo ifconfig eth0 up> ,請問我需要點做? THX

Put all this in a text file, say name as net.reset.sh

1. #!/bin/bash
   
2. cat /proc/net/arp
   
3. ifconfig eth0 down && ifconfig eth0 up

複製代碼

1. command line type:-
   
2. chmod 700 net.reset.sh
   
3. sudo chown root:root net.reset.sh
   
4. sudo ./net.reset.sh

複製代碼

net.reset.sh 要 sudo 先可以 del/edit

係咁上下

解決了,我閞頭以為要set $xx=incomplete 後set if $xx then 乜乜乜
原來只需cat /proc/net/arp | grep -q incomplete
then sudo ifconfig eth0 down
sudo ifconfig eth0 up

cal22cal

assign variable 就咁 xx=incomplete
直接 grep 就可以喇，唔洗 cat

1. grep -iqs "incomplete" /proc/net/arp && { sudo ifconfig eth0 down && sduo ifconfig eth0 up; }
