Make netstat human readable?
Is there any way to make netstat output the information in a more human readable format? even if it's not exact? I don't even care if it has to round up/down to the nearest Meg to make it work.

I wind up having to stare at netstat running for while and I wish I could get it to output things in a format like 45M instead of 47395923 or other rediculously long numbers that I can't read at a glance.

Why would netstat be showing this info? what options/flags are you using with it? By default netstat shows listening ports and hosts/clients.

Also, what OS are you running ?

Running freebsd with bash.

Mostly i'm using it to watch overall throughput through the interfaces.

So normally all i'm doing is.

Code:
netstat -i 1 1

So i'll leave netstat running for a very long time and then scroll back through history looking for spikes in traffic and such trying to determine if the system is pushing too much traffic. If I could get it to display in more human readable numbers it would make life easier.

You could pipe it through awk or something to get human readable, paste some of your output here and we can help you.

Typical output would be something like this.
Code:
[/root]$ netstat -i 8 1
            input        (Total)           output

Ok so I've figured out how to do some math using Awk and I can get it to do the math on the columns that I want... Question now is how to do the math to get the output to be a nice clean easy to read number.
So now I need to convert 41408832 bytes into megabytes with no decimal places.

---------- Post updated at 03:56 PM ---------- Previous update was at 03:50 PM ----------

Code:
netstat -i 1 1 | awk '{print $3/1024/1024}'

ok so now I just gotta figure out how to get rid of the decimal places.
