UPSRW(8) Network UPS Tools (NUT) UPSRW(8)NAMEupsrw - UPS variable administration tool
SYNOPSISupsrw ups
upsrw-h
upsrw-s variable [-u username] [-p password] ups
DESCRIPTIONupsrw allows you to view and change the read/write vari-
ables inside your UPS. It sends commands via the server
upsd(8) to your driver, which configures the hardware for
you.
The list of variables that allow you to change their val-
ues is based on the capabilities of your UPS equipment.
Not all models support this feature. Typically, cheaper
hardware does not support any of them. Run upsrw with a
UPS identifier to see what will work for you.
OPTIONS-h Display the help message.
-s variable
Specify the variable to be changed inside the UPS.
For unattended mode such as in shell scripts, use
the format VAR=VALUE to specify both the variable
and the value, for example:
-s HIGHXFER=129
Without this argument, upsrw will just display the
list of the variables and their possible values.
Some variables are strings, and can be set to any
value within the length limit. Others are enumer-
ated types and can only be set to one of those val-
ues. Refer to the list to know what's available in
your hardware.
-u username
Set the username for the connection to the server.
This is optional, and you will be prompted for this
when using the -s option if you don't specify -u on
the command line.
-p password
Set the password to authenticate to the server.
This is also optional like -u, and you will be
prompted for it if necessary.
ups View or change the settings on this UPS. The for-
mat for this option is [upsname@]hostname[:port].
UNATTENDED MODE
If you run this program inside a shell script or similar
to set variables, you will need to specify all of the
information on the command line. This means using -s
VAR=VALUE, -u and -p. Otherwise it will put up a prompt
and your program will hang.
This is not necessary when displaying the list, as the
username and password are not required for read-only mode.
DIAGNOSTICSupsrw can't set variables on your UPS unless you provide a
valid username and password. If you get "access denied"
errors, make sure that your upsd.users(5) has an entry for
you, and that the username you are using has permissions
to SET variables.
HISTORY
This program used to be called upsct2, which was ambiguous
and confusing.
