• Linux

Overview

lsof lists information about files opened by processes. lsof provides information about:

• regular files
• directories
• block special files
• character special files
• executing text references
• libraries
• streams
• network files (Internet socket, NFS file or UNIX domain socket)

In absence of any options, lsof lists all open files by all processes.

To list open files by a specific process, use the process' PID as follows:

lsof -p <pid>
