Anyway to run sudo command and getting output?

In ubuntu I can get the networking traffic details via

$ sudo iftop -t -s 1 -L 10

which gives result like this

interface: eth0
IP address is: 192.168.150.2
MAC address is: c0:3f:d5:f6:cb:d3
Listening on eth0

But we know we used sudo there. I am working for page in university where i can show this result interactivly probably on charts. But I cannot get the output as it need sudo command .

I made command like this

$ php artisan university:internet

Which in turn calls that sudo command

I know it will give permissions error? Any way or hack to make it possible?

Thanks

To peek in on the interface traffic with this tool you need user permission to view that traffic. This is why you have to sudo. Allowing other users on the system to see this traffic would be a huge security hole - don't try that.

One thing you could do, is install a process, as root, that will run this command for you and log the output somehow. This way, you could have your artisan process with permission to read that log file, and then do the processing you want from that. This would make more sense to me - and would be much more secure.

Using cron could certainly be one way to do it. Seems that iftop has different output modes - some of those alternatives may be better for your purposes.

I'm not sure what you're shooting for here...

@burlresearch i just want those text to be in some file and updated regularly like 10 second so i can show live updates in website.

Sure, then you could create a shell-script like this, that will write a bunch of files for you:

#!/bin/bash

i=3

while [ $i -gt 0 ]; do
    s=`date +%s`
    iftop -i eth0 -t -s 1 -L 10 > iftop-${s}.dat
    echo $i
    ((i--))
done

and when you're done tweaking that you can replace with while true; do
