lsof:tldr:e93b3
lsof: Find the process that opened a local internet port.
$ lsof -i :${port}
try on your machine
The command "lsof -i :${port}" is used in Unix-based operating systems to list open internet connections or network sockets listening on a specific port.
Here is a breakdown of the command:
- "lsof" stands for "List Open Files" and is a command used to display information about files and processes that have them open.
- "-i" is an option for lsof, which specifies that we want to list internet (network) files.
- ":${port}" is a parameter that should be replaced with the specific port number you want to check. For example, if you want to see the processes using port 80, you would replace
${port}
with80
.
Overall, the command queries the system for any processes that have network sockets open and are listening on a specific port. It provides information about those processes, such as the process ID (PID), user, file descriptor, type of connection (TCP or UDP), and associated program or command.

never run a command you are not sure if it is safe.
