lsof

Lists open files and the corresponding processes Note: In most cases, you need root privilege (or use sudo) because you want to list files opened by others

  • Find the processes that have a given file open:

lsof {{/path/to/file}}

  • Find the process that opened a local internet port:

lsof -i :{{port}}

  • only output the process PID

lsof -t {{/path/to/file}}

  • list files opened by the given user

lsof -u {{username}}

  • list files opened by the given command or process

lsof -c {{process_or_command_name}}
