.TH FINDDEV 8 
.SH NAME
finddev \- find processes using a device
.SH SYNOPSIS
.B /etc/finddev
[ pid ] ...
[ file ] ...
.SH DESCRIPTION
When invoked without arguments,
.I finddev
prints the number of every process
and a description of each file referred to
by that process.
Giving one or more process numbers
restricts
.IR finddev 's
attention to those processes.
.PP
If file arguments appear,
.I finddev
prints only the process numbers of those
processes that refer to files in the
argument list.
If an argument file is an ordinary file,
character special file,
or directory, the process must refer to that
file to be counted.
If an argument is a block special file
containing a mounted file system,
a process will be counted if it refers to any
file on that file system.
.PP
To see details of all processes referring to, say, the console, try:
.IP
finddev \(gafinddev /dev/console\(ga
.PP
.I Finddev
has no special privileges.
To use it, the user must have permission to read
.IR /dev/mem .
