list

portcheck list

List sockets and the processes that own them

Synopsis

List local TCP and UDP sockets together with their owning process.

Without elevated privileges some owners may be hidden; portcheck prints a hint when that happens.

portcheck list [flags]

Examples

  portcheck list --listening
  portcheck list --port 3000-3999 --proto tcp

  portcheck list -l --watch 2s
