fkill-cli terminates processes on macOS, Linux, and Windows from the command line.
About FKill
fkill-cli is a command-line tool that ends running processes on macOS, Linux, and Windows. It can target a process by its process ID, by its name, or by a port number written with a leading colon, such as :8080. Running it without arguments opens an interactive interface that supports fuzzy search.
The interactive interface marks processes with high CPU usage and high memory usage using indicator symbols. Name matching is case-insensitive by default, and a case-sensitive option is available. The package is open source under the MIT license and is installed with npm. Pricing information is not stated in the source.
