HAL-SET-PROPERTY(1)                                                                                          HAL-SET-PROPERTY(1)



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.


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  privi-
       leges.


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