NAME

       halevt - Generic handler for HAL events

SYNOPSIS

       halevt [options]

DESCRIPTION

       Halevt is a daemon that executes arbitrary commands when a device with certain properties is added to the system and when device properties
       change, using HAL.  Unless a configuration file is given on the command line with the -c option, configuration files are  searched  for	in
       $HOME/.halevt, /etc/halevt, and /usr/share/halevt (in that order). All the files ending with .xml found in these directories are considered
       to be configuration files. If a file with the same name has already been found in a previous directory, it is ignored. Default  for  halevt
       is to run as a daemon in the background.

       Halevt  may also be run in another mode, called the reporting mode, turned on by the -i option. In that case no config file is read, Halevt
       stays in the foreground and report all the HAL events.

OPTIONS

       -c file
	      Use configuration file file.

       -d     Give debugging informations and stay in the foreground.

       -f     Stay in the foreground.

       -g group
	      Run as group group, if started by the root user. Default is to run as halevt.

       -h     Help message and options summary.

       -i     Run in reporting mode. No configuration file is read, and halevt stays in the foreground, reporting all the HAL events.

       -p pidfile
	      Use pid file pidfile to store the daemon pid, instead of the default.  Default is /var/run/halevt.pid if run as root  user,  and	no
	      pid file if run as a user. - means no pidfile.

       -u user
	      Run as user user, if started by the root user. Default is to run as halevt.

NAME

       hald - HAL daemon

SYNOPSIS

       hald [options]

DESCRIPTION

       hald  is  a  daemon  that maintains a database of the devices connected to the system system in real-time. The daemon connects to the D-Bus
       system message bus to provide an API that applications can use to discover, monitor and invoke operations on devices. For more  information
       about  both  the  big  picture  and specific API details, refer to the HAL spec which can be found in /usr/share/doc/packages/hal/spec/hal-
       spec.html depending on the distribution.

OPTIONS

       The following options are supported:

       --daemon=yes|no
	      Specify whether to run in the foreground or the background.

       --verbose=yes|no
	      Enable verbose debug output.

       --use-syslog
	      Enable logging of debug output to the syslog instead of stderr. Use this option only together with --verbose.

       --help Print out usage.

       --version
	      Print the version of the daemon and exit.

BUGS AND DEBUGGING

       Please send bug reports to either the distribution or the HAL mailing list, see http://lists.freedesktop.org/mailman/listinfo/hal on how to
       subscribe.

       First,  to  obtain  useful debug traces you will need to have debuginfo packages installed. On a Fedora system this is in the hal-debuginfo
       package and can be installed via the yum update program.

       Second, shut down the existing hald daemon instance; on a Fedora system this is achieved by

       /etc/init.d/haldaemon stop

       After having shut down the daemon, you might want to run

       pkill hald

       to ensure that all the helper processe of hald are killed too. To start the HAL daemon, use

       /usr/sbin/hald --daemon=no --verbose=yes

       If the daemon crashes, you can start it under a debugger via

       gdb /usr/sbin/hald

       and then typing

       run --daemon=no --verbose=yes

       at the (gdb) prompt. To capture a back trace, use the bt command and attach this to the bug report.

       Please also attach the output of lshal(1) in the bug report if possible (it's not possible if the hald daemon crashed). If  the	nature	of
       the bug has to do with hotplugging, attach two outputs of lshal(1) - one before the device hotplug event and one after.
