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/local/share/doc/hal/spec/hal-spec.html depending on the
       distribution.

       --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.

              false.

       --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.
