13 real-time thermal data; tune
22 - show thermal zone information
23 - show cooling device information
24 - show trip point binding within each thermal zone
25 - show trip point and cooling device instance bindings
28 - show temperature of all thermal zones w.r.t. its trip points and types

46 The \fB-c --control\fP option sets a cooling device type to control temperature
49 The \fB-d --daemon\fP option runs \fBtmon \fP as daemon without user interface
51 The \fB-g --debug\fP option allow debug messages to be stored in syslog
53 The \fB-h --help\fP option shows help message
55 The \fB-l --log\fP option write data to /var/tmp/tmon.log
57 The \fB-t --time-interval\fP option sets the polling interval in seconds
59 The \fB-T --target-temp\fP option sets the initial target temperature
61 The \fB-v --version\fP option shows the version of \fBtmon \fP
63 The \fB-z --zone\fP option sets the target therma zone instance to be controlled
