NAME¶
upsrw - UPS variable administration toolSYNOPSIS¶
upsrw upsDESCRIPTION¶
upsrw allows you to view and change the read/write variables inside your UPS. It sends commands via the server upsd(8) to your driver, which configures the hardware for you.OPTIONS¶
-hDisplay 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:
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 enumerated types and can only be set to one of those values. Others
may be within an allowed range of values. Refer to the list to know
what’s available in your hardware.
-u username
-s input.transfer.high=129
Set the NUT 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. NUT usernames are
defined in upsd.users(5), and are not linked to system usernames.
-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
format for this option is upsname[@hostname[:port]]. The default hostname is
"localhost".
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.DIAGNOSTICS¶
upsrw 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.SEE ALSO¶
