Bandwhich – A Network Bandwidth Utilization Tool for Linux

Bandwhich, formerly known as “what”, is a terminal utility written in Rust programming language, which is used for monitoring current network bandwidth utilization by the process, connection, and remote IP/hostname. It sniffs a specified network interface and tracks IP packet size, cross-referencing it with the /proc filesystem on Linux and lsof on macOS.
