kill specific port code example

Example 1: kill process on port

#To list any process listening to the port 8080:
lsof -i:8080

#To kill any process listening to the port 8080:
kill $(lsof -t -i:8080)

#or more violently:
kill -9 $(lsof -t -i:8080)

Example 2: kill port

kill -9 $(sudo lsof -t -i:8080)

Example 3: kill process on port

# To list any process listening to the port 8080:
lsof -i:8080

# To kill any process listening to the port 8080:
kill $(lsof -t -i:8080)

# or more violently:
kill -9 $(lsof -t -i:8080)
# (-9 corresponds to the SIGKILL - terminate immediately/hard kill signal: see List of Kill Signals and What is the purpose of the -9 option in the kill command?. If no signal is specified to kill, the TERM signal a.k.a. -15 or soft kill is sent, which sometimes isn't enough to kill a process.).

Example 4: kill port

lsof -i:8080

Example 5: kill port

kill -9 $(sudo lsof -t -i:'portName')
//Ex. if portname is 3000
//then we will execute "kill -9 $(sudo lsof -t -i:3000)"

Example 6: kill port

:8080.
