fuser: Identify processes using a TCP socket.
$ fuser --namespace tcp ${port}
try on your machine
The command "fuser --namespace tcp ${port}" is used to check which process is using a specific TCP port.
Here's the breakdown of the command:
- "fuser" is the command-line utility used for displaying information about which processes are using specific files, directories, or network connections.
- "--namespace tcp" is an option provided by the "fuser" command to specify that we are interested in TCP ports.
- "${port}" is a placeholder for the specific port number that you want to check. You need to replace "${port}" with the actual port number you intend to investigate.
By executing this command with the desired port number, the system will return the process ID (PID) of the process that is currently using that TCP port.
