NAME
hal-get-property, hal-set-property - get and set HAL device properties SYNOPSIS
hal-get-property --udi udi --key key [--help] [--verbose] [--version] hal-set-property --udi udi --key key {--int value | --uint64 value | --string value | --bool value | --strlist-pre value | --strlist-post value | --strlist-rem value | --double value | --remove value} [--help] [--version] DESCRIPTION
The Hardware Abstraction Layer (HAL) provides a view of the various hardware attached to a system. This view is updated dynamically as hardware configuration changes by means of hotplug or other mechanisms. HAL represents a piece of hardware as a device object. A device object is identified by a unique identifer and carries a set of key/value pairs, referred to as device properties. Some properties are derived from the actual hardware, some are merged from device information files (.fdi files), and some are related to the actual device configuration. The hal-get-property and hal-set-property commands allow you to get and set properties of hardware that conforms to HAL specifications. OPTIONS
The following options are supported: --udi udi Unique device ID. --key key Key of the property to set. --int Set value to an integer. Accepts decimal or hexadecimal value prefixed with 0x or x. --uint64 Set value to an integer. Accepts decimal or hexadecimal value prefixed with 0x or x. --string value Set value to a string. --double value Set value to a floating point number. --boolean value Set value to a boolean, that is, true or false --strlist-pre value Prepend a string to a list. --strlist-post value Append a string to a list. --strlist-rem value Remove a string from a list. --remove value Indicates that the property should be removed. --version Display version and exit. --help Display list of options and exit ATTRIBUTES

NAME
hal-set-property - set a property on a device object SYNOPSIS
hal-set-property [options] DESCRIPTION
hal-set-property sets a property on a device object in the HAL device database. For more information about both the big picture and spe- cific HAL properties, refer to the HAL spec which can be found in /usr/share/doc/hal-doc/spec/hal-spec.html depending on the distribution. OPTIONS
The following options are supported: --udi The UDI (Unique Device Identifier) of the device object. --key The name of the property. --int Set value property of the property to a 32-bit signed integer. The value passed is assumed to be decimal unless it's prefixed with 0x or x for hexadecimal values. --uint64 Set value property of the property to a 64-bit unsigned integer. The value passed is assumed to be decimal unless it's prefixed with 0x or x for hexadecimal values. --string Set value property of the property to a string. --double Set value property of the property to a floating point number. --bool Set value property of the property to boolean, e.g. true or false. --strlist-pre Prepend an item to a string list. --strlist-post Append an item to a string list. --strlist-rem Remove an item from a string list. --remove Remove a property. --help Print out usage. --version Print the version. RETURN VALUE
If setting the property succeeds, this program will exit with exit code 0. On errors a non-zero the program will exit with a non-zero exit code. Note that setting properties on the HAL device database usually requires super user privileges. BUGS
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. SEE ALSO
