Version: 4.15

A PGP signature is provided for the source inside the tar wrapper.

Description:

    Lsof lists information about files opened by processes
    for the UNIX dialects listed below.

    An open file may be a regular file, a directory, a block special
    file, a character special file, an executing text reference, a
    library, a stream or a network file (Internet socket, NFS file or
    UNIX domain socket.) A specific file or all the files in a file
    system may be selected by path.

    The lsof output describes:

    * the identification number of the process (PID) that opened the file;
    * the process group identification number (PGRP) of the process (optional);
    * the identification number of the parent process (PPID) (optional);
    * the command the process is executing;
    * the owner of the process;

    For all files in use by the process - including the executing
    text file and the shared libraries it is using - lsof also reports:

    * the file descriptor number of the file, if applicable;
    * the file's access mode;
    * the file's lock status;
    * the file's device numbers;
    * the file's inode number;
    * the file's size or offset;
    * the name of the file system containing the file;
    * any available components of the file's path name;
    * the names of the file's stream components;
    * the file's local and remote network addresses;
    * other file or dialect-specific values.
