You can try netstat netstat -vanp tcp grep For macOS El Capitan and newer or if your netstat doesn't support -p , use lsof lsof -i tcp For Centos 7 use: netstat -vanp --tcp grep Improve this answer.

Another tip is to add -P to the lsof command so that the raw port is visible in the output: lsof -P -i — Jason Axelson. This post is only half the answer — png. Show 8 more comments. Filip Spiridonov Filip Spiridonov Sometimes lsof -i :port will show nothing. MichaelTrouw almost a year later, but here's your answer. I think this answer should say what -9 does. Please don't just use kill -9 without thinking twice, and trying other signals first.

Yours was 6 months earlier, and has the same information with a bit more explanation. There is no justice A one-liner to extract the PID of the process using port and kill it.

This method works best for me. Simple one liner that clears the busy port. This single command line is easy to remember: npx kill-port You can also kill multiple ports at once: npx kill-port For a more powerful tool with search: npx fkill-cli PS: They use third party javascript packages.

I tried installing it on my Mac High Sierra, Just upgrade your node.
