I am trying to kill a proccess in the command line for a specific port in ubuntu.
If I run this command I get the port:
sudo lsof -t -i:9001
so...now I want to run:
sudo kill 'sudo lsof -t -i:9001'
I get this error message:
ERROR: garbage process ID "lsof -t -i:9001".
Usage:
kill pid ... Send SIGTERM to every process listed.
kill signal pid ... Send a signal to every process listed.
kill -s signal pid ... Send a signal to every process listed.
kill -l List all signal names.
kill -L List all signal names in a nice table.
kill -l signal Convert between signal numbers and names.
I tried sudo kill 'lsof -t -i:9001' as well
You want to use backtick not regular tick:
sudo kill `sudo lsof -t -i:9001`
If that doesn't work you could also use $() for command interpolation:
sudo kill $(sudo lsof -t -i:9001)
FOR UBUNTU 1- Find what application/process is using the pro, type:
sudo netstat -lpn |grep :8080
and press Enter.
You will get an output similar to this one
tcp6 0 0 :::8080 :::* LISTEN 6782/java
2- I have got the process Id, which is 6782, now this is the process that is using port 8080.
3- Kill the process, type:kill 6782
kill 6782
There are some process which does not shown using normal netstat command, so you have to check it using sudo.
Do sudo netstat -lpn |grep :8080. Process running by system does not show PID, to get PID of this process you will have to run it using sudo
And then killl the process using port 8080. You may have to use sudo here as well. So to kill this process use sudo kill -9 PID
The best way to kill a port in ubuntu terminal is
fuser -k 9001/tcp
Use killport command :
sh killport 9001
To Download shell ,you can use wget :
wget https://cdn.rawgit.com/abdennour/miscs.sh/e0aac343/killport
You may also use fuser to do that (sends SIGKILL by default):
sudo fuser -k 9001/tcp
To kill on port service in ubuntu, Enter the below command in terminal
In Terminal :
sudo fuser -k port/tcp
sudo fuser -k 8001/tcp
To kill the process based on port first we have to find out the relevant pid for given port and kill using that pid,
In my case i wanted to get the pid(process id) of 3000 port:
netstat -ltnp | grep -w '3000'
then find pid which is listening to tcp
tcp6 0 0 :::3000 :::* LISTEN 29972/node
you will get pid 29972
To kill this pid use below command
kill -9 29972
pseudo code for kill process based on port
netstat -ltnp | grep -w 'PORT'
and
kill -9 PID
Use this:
sudo kill -9 $(lsof -t -i:9001)
To kill a process running on Port number 9001
sudo kill -9 $(sudo lsof -t -i:9001)
lsof - list of files(Also used for to list related processes)
-t - show only process ID
-i - show only internet connections related process
:9001 - show only processes in this port number
kill - command to kill the process
-9 - forcefully
sudo - command to ask admin privilege(user id and password).

Kill PORT:
sudo is important to show process id.
$ sudo netstat -antlp | grep 45136
tcp 0 0 0.0.0.0:45136 0.0.0.0:* LISTEN **-**
$ kill -9 45136
Try this:
lsof -i :port
or
sudo kill $(sudo lsof -t -i:8000)
or
kill -9 <pid>
or
sh killport 8000
Use the command
netstat -plten |grep java
used grep java as tomcat uses java as their processes.
It will show the list of processes with port number and process id
tcp6 0 0 :::8080 :::* LISTEN
1000 30070621 16085/java
the number before /java is a process id. Now use kill command to kill the process
kill -9 16085
-9 implies the process will be killed forcefully.
just enter
fuser -k -n tcp 3000
in terminal , where 3000 is your port number
Use this for killing process which is running on port number "9001"
kill $(lsof -t -i:9001)
Its two steps process:
- Know process id on port no. 8080 (can be any)
Kill process of that id 8689 (can be different)
fuser -n tcp 8080 #o/p 8080/tcp 8689 kill -9 8689
you can work this using node
npm install freethenport -g
then
node freethenport 9001
Try sudo fuser PORT/tcp -k
Replace PORT with the port you want to kill, for example 80
sudo kill `sudo lsof -t -i:9001`
you don't have to add the -9signal option
Displays active TCP connections, ports on which the computer is listening.
netstat -tupln
It will list you all the connection along pid. Find and copy the pid and run the following command. Make sure you replace the with actual id in the following command.
kill -9 <copied pid>
-9 use to forcefully kill the connection.
sudo fuser -n tcp -k 3000
sudo lsof -t -i:3000
sudo kill $(sudo lsof -t -i:1337)
