(See the DISTRIBUTION section of this manual page for information on
how to obtain the latest lsof revision.)
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.
Instead of a formatted display, lsof will produce output that can be
parsed by other programs. See the -F, option description, and the OUT-
PUT FOR OTHER PROGRAMS section for more information.
In addition to producing a single output list, lsof will run in repeat
mode. In repeat mode it will produce output, delay, then repeat the
output operation until stopped with an interrupt or quit signal. See
