Working a script differently for two rang of IPs

massy · 03-21-2014, 04:04 PM

Code:

 while read IP
 do
        rm -f rbtdate.txt
        rm -f rbt.txt
        ssh -n  $usr@$IP 'hostname;date +%T;head -1 /dev/ttyS1;uptime;last reboot|head -30' >rbt.txt
        host=`head -1 rbt.txt|cut -c 5-8`
        RSUname=`_RSUhostname`

This is the part of my script to do some commands via ssh and show some outputs, when I run it with IP rang in 192.168.40.X, it works correctly! But when I run it with 10.8.0.X, it remains in the orange line! and I should press Ctrl+c to continue the script and reading next IP via the loop.Before that the next IP would be read, the output is shown, but I want to run it automatically without pressing Ctrl+c !

Code:

head -1 /dev/ttyS1

What do you think this line does?

It reads a file that keep the temperature!
The script worked correctly before that I test it with IP range in 192.168.40.X !!!

No, /dev/ttyS1 isn't a file that keeps the temperature.
