.TH MOTION 1 2006-10-16 "Motion" "Motion Options and Config Files"
.SH NAME
motion \-   Detect motion using a video4linux device
.SH SYNOPSIS
.B motion
[ -hns ] [ -c config file path]
.SH DESCRIPTION
.I  Motion
uses a video4linux device to detect motion. If motion is detected both normal
and motion pictures will be taken. Motion can also take actions to notify you
if needed. Creation of automated snapshots is also possible.
.SH OPTIONS
.TP
.B \-c
Full path and filename of config file. E.g. /home/kurt/motion.conf. Default is /usr/local/etc unless specified differently when building Motion. Many RPMs and debian packages will most likely use /etc or /etc/motion as default.
.TP
.B \-h
Show help screen.
.TP
.B \-n
Run in non-daemon mode.
.TP
.B \-s
Run in setup mode. Also forces non-daemon mode
.TP
.B \-d
Run in debug mode.
.TP
.B \-p
Full path and filename for process id file (pid file). E.g /var/run/motion.pid. Default is not defined. Pid file is only created when Motion is started in daemon mode.
