A simple CLI tool to check if and which PID uses a given port number and optionally kill it.
npm i -g whoport
- OSX 10.10.5, 10.11.4
- Windows 7
- Debian 7.8 (wheezy)
Due to the use of
netstat for Windows operating systems, whoport should also work on Windows Vista and above. (thanks @lewisje for the hint!)
How it works
- OSX uses
lsofto check for processes and
kill -9to kill one or more PIDs.
- Windows uses
netstatto check for processes and
taskkillto kill the PID.
# check and display PID if present whoport 9090 # kill process which uses port whoport 9090 -k
No process found but something is listening. (OSX)
You need to execute whoport with sudo if a process runs via another or root user. Also see man lsof section "Security".
