PROGRAM
Let udev execute an external program. To be successful, the program must return
with exit code zero. The program's output, printed to stdout, is available to the
RESULT key.
RESULT
Match the output string of the last PROGRAM call. Either include this key in the
same rule as the PROGRAM key or in a later one.
11.6.4 Using udev Assign Keys
In contrast to the match keys described above, assign keys do not describe conditions
that must be met. They assign values, names and actions to the device nodes maintained
by udev.
NAME
The name of the device node to be created. Once a rule has set a node name, all
other rules with a NAME key for this node are ignored.
SYMLINK
The name of a symlink related to the node to be created. Multiple matching rules
can add symlinks to be created with the device node. You can also specify multiple
symlinks for one node in one rule using the space character to separate the symlink
names.
OWNER, GROUP, MODE
The permissions for the new device node. Values specified here overwrite anything
that has been compiled in.
ATTR{key}
Specify a value to be written to a sysfs attribute of the event device. If the == oper-
ator is used, this key is also used to match against the value of a sysfs attribute.
ENV{key}
Tell udev to export a variable to the environment. If the == operator is used, this
key is also used to match against an environment variable.
