.Sh DESCRIPTION
|
|
|
|
|
.Nm
|
|
|
|
|
displays sensor readings from any device which supports the
|
|
|
|
|
.Xr envsys 4
|
|
|
|
|
API. Readings are displayed in columns, one column per sensor. Column
|
|
|
|
|
widths as well as displayed sensors are fully customizable. The column
|
|
|
|
|
headers display the name (stored in the device driver) as well as
|
|
|
|
|
the units of each sensor.
|
|
|
|
|
.Pp
|
|
|
|
|
The options are as follows:
|
|
|
|
|
.Bl -tag -width flag
|
|
|
|
|
.It Fl f
|
|
|
|
|
Display any temperature values in degrees Fahrenheit. The default is to
|
|
|
|
|
display temperature values in degrees Celsius.
|
|
|
|
|
.It Fl l
|
|
|
|
|
List the names of all supported sensors, one per line. Use of this
|
|
|
|
|
flag causes
|
|
|
|
|
.Nm
|
|
|
|
|
to ignore all other option flags.
|
|
|
|
|
.It Fl i
|
|
|
|
|
Repeat the display every
|
|
|
|
|
.Ar interval
|
|
|
|
|
seconds. Note that some devices do not provide fresh values on demand.
|
|
|
|
|
See the individual device's manual page for meaningful values for
|
|
|
|
|
.Ar interval .
|
|
|
|
|
If not specified, or specified as 0,
|
|
|
|
|
.Nm
|
|
|
|
|
produces one line of values and exits.
|
|
|
|
|
.It Fl n
|
|
|
|
|
Display a new header every
|
|
|
|
|
.Ar headrep
|
|
|
|
|
lines. An argument of 0 disables header line printing completely.
|
|
|
|
|
The default is every 22 lines.
|
|
|
|
|
.It Fl s
|
|
|
|
|
Restrict the display to the named sensors. The sensor names must be
|
|
|
|
|
supplied as a comma separated list. Sensor names are case sensitive.
|
|
|
|
|
.It Fl w
|
|
|
|
|
Use
|
|
|
|
|
.Ar width
|
|
|
|
|
as the column width for the output. Each column is additionally separated
|
|
|
|
|
by a single space. The default is either the length of the longest sensor
|
|
|
|
|
name or spread evenly to fill 80 columns, whichever is greater.
