chronos@localhost / $ crossystem --help
Invalid parameter name: --help
Usage:
crossystem [--all]
Prints all parameters with descriptions and current values.
If --all is specified, prints even normally hidden fields.
crossystem [param1 [param2 [...]]]
Prints the current value(s) of the parameter(s).
crossystem [param1=value1] [param2=value2 [...]]]
Sets the parameter(s) to the specified value(s).
crossystem [param1?value1] [param2?value2 [...]]]
Checks if the parameter(s) all contain the specified value(s).
Stops at the first error.
