hal-set-property - set a property on a device object
hal-set-property sets a property on a device object in the HAL device database. For more information about both the big picture and specific HAL properties, refer to the HAL spec which can be found in /spec/hal-spec.html depending on the distribution.
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 its 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 its 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.
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.
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.
