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  specific  HAL  properties,  refer  to  the   HAL   spec   which   can   be   found   in
       /usr/share/doc/hal-0.5.14/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 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 deci-
              mal 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.

              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.
