imsnif / what, Hacker News

This is a CLI utility for displaying current network utilization by process, connection and remote IP / hostname

How does it work?

whatsniffs a given network interface and records IP packet size, cross referencing it with the/ procfilesystem on linux orlsofon MacOS. It is responsive to the terminal window size, displaying less info if there is no room for it. It will also attempt to resolve ips to their host name in the background using reverse DNS on a best effort basis.



yay -S whatMacOS and other Linux flavorscargo install whatIf you're on linux, you could also get the generic binary from the releases.
Windows is not supported at the moment - if you'd like to contribute a windows port, it would be very much welcome.
Usage

what  Also supports an easier-to-parse mode that can be piped or redirected to a file. For example, try:
what --raw | grep firefox
