I want to get the current Bandwidth of an interface say "eth0" from the terminal. It better be as simple as possible. Say up 10 dn 30. Instead of giving out a lot of text like "vnstat" does.

Edit: I need this for a command line program for auto-monitoring, not to view it manually.

you could try iftop – Alexej Magura Dec 24 '13 at 19:06

There are several tools that can do this.


One that should be in most repositories for various distros is bmon.

    ss of bmon

It can be run in a condensed view too.

           ss of bmon small

If you're looking for something else I'd suggest taking a look at this Linuxaria article titled: Monitor your bandwidth from the Linux shell. It also mentions nload as well as speedometer.


    ss of nload


            ss of speedometer


If you're looking for something more basic then you could also give ibmonitor a go. Though basic it has most of the features one would expect when monitoring bandwidth.

And don't forget iftop. – n.st Dec 1 '13 at 17:02
@n.st - familiar with it, but didn't mention it since he wanted bandwidth methods, and that shows per process, similar to top. – slm Dec 1 '13 at 17:07
It does display the total bandwidth too, but I'll agree that it's probably less than ideal for automatic evaluation by a script like the OP intends to. – n.st Dec 1 '13 at 17:09
@n.st - yeah that's why I left it out, but I do use it regularly for finding mis-behaving network users 8-) – slm Dec 1 '13 at 17:10

You can also use Linux process explorer. It can monitor bandwidth usage per process.

While this link may answer the question, it is better to include the essential parts of the answer here and provide the link for reference. Link-only answers can become invalid if the linked page changes. – manatwork Dec 24 '13 at 12:51
The question asked for a command-line program. – Gilles Dec 24 '13 at 17:22
