To find the complete path of a process that is using a specific port in Linux, you can follow these steps:
Step 1: Find the PID of the Process
1. Using `lsof` Command**:
- Open a terminal and run the following command (replace `PORT_NUMBER` with the actual port number):
--------------------------------------------------------------------
sudo lsof -i :PORT_NUMBER
--------------------------------------------------------------------
- This command will list all processes using the specified port, along with their PIDs.
2. Using `netstat` Command**:
- Alternatively, you can use the `netstat` command:
--------------------------------------------------------------------
sudo netstat -tulpn | grep :PORT_NUMBER
--------------------------------------------------------------------
- This will show you the PID and the program name associated with the port.
Step 2: Get the Complete Path of the Process
Once you have the PID from the previous step, you can find the complete path of the process:
1. Using `ps` Command**:
- Run the following command (replace `YOUR_PID` with the PID you obtained):
--------------------------------------------------------------------
ps -p YOUR_PID -o args=
--------------------------------------------------------------------
- This command will display the command line that started the process, including the complete path.
2. Using `/proc` Filesystem**:
- You can also check the `/proc` filesystem for more details:
--------------------------------------------------------------------
ls -l /proc/YOUR_PID/exe
--------------------------------------------------------------------
- This will show you a symbolic link to the executable of the process, revealing its complete path.
