Mac: number of bytes transmitted over interface

Question

On linux, I'm used to typing ifconfig and looking for the line with "RX bytes" and "TX bytes" in it to find out how many bytes have been received and transmitted over a particular interface since boot. The line looks like this:

      RX bytes:106951129 (101.9 MB)  TX bytes:1577761831 (1.4 GB)

I tried running the same command in a terminal on a Mac (OS X, version 10.4.11) but didn't see this data anywhere. How do I get the same information from a Mac?

Edit: This is a test server, meant to simulate a typical out-of-the-box Mac install. So I need to avoid installing any programs if I can. A command-line tool would be ideal.

Answer 1

netstat -ib

seems to do the trick. Thanks to nik for pointing in the right direction. (Putting the result in a new answer so as not to make future readers dig through comments.)

Answer 2

The easiest way I know of seeing bytes in/out over an interface (w/o command line) is with MenuMeters. You can see all that info right on the top bar so it's always visually accessible.

Answer 3

Try ifconfig -a.
But, I suspect there is a better command for the OSX.
It is discouraged to use the ifconfig command in OSX like its used in Linux.

check networksetup or netstat.
