.SH "NAME"
|
|
upsrw \- UPS variable administration tool
|
|
.SH "SYNOPSIS"
|
|
.sp
|
|
\fBupsrw\fR \fIups\fR
|
|
.sp
|
|
\fBupsrw\fR \-h
|
|
.sp
|
|
\fBupsrw\fR \-s \fIvariable\fR [\-u \fIusername\fR] [\-p \fIpassword\fR] \fIups\fR
|
|
.SH "DESCRIPTION"
|
|
.sp
|
|
\fBupsrw\fR allows you to view and change the read/write variables inside your UPS\&. It sends commands via the server \fBupsd\fR(8) to your driver, which configures the hardware for you\&.
|
|
.sp
|
|
The list of variables that allow you to change their values 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\&.
|
|
.SH "OPTIONS"
|
|
.PP
|
|
\fB\-h\fR
|
|
.RS 4
|
|
Display the help message\&.
|
|
.RE
|
|
.PP
|
|
\fB\-s\fR \fIvariable\fR
|
|
.RS 4
|
|
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:
|
|
.sp
|
|
.if n \{\
|
|
.RS 4
|
|
.\}
|
|
.nf
|
|
\-s input\&.transfer\&.high=129
|
|
.fi
|
|
.if n \{\
|
|
.RE
|
|
.\}
|
|
.sp
|
|
Without this argument, upsrw will just display the list of the variables and their possible values\&.
|
|
.sp
|
|
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\(cqs available in your hardware\&.
|
|
.RE
|
|
.PP
|
|
\fB\-u\fR \fIusername\fR
|
|
.RS 4
|
|
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\(cqt specify \-u on the command line\&. NUT usernames are defined in
|
|
\fBupsd.users\fR(5), and are not linked to system usernames\&.
|
|
.RE
|
|
.PP
|
|
\fB\-p\fR \fIpassword\fR
|
|
.RS 4
|
|
Set the password to authenticate to the server\&. This is also optional like \-u, and you will be prompted for it if necessary\&.
|
|
.RE
|
|
.PP
|
|
\fIups\fR
|
|
.RS 4
|
|
View or change the settings on this UPS\&. The format for this option is
|
|
upsname[@hostname[:port]]\&. The default hostname is "localhost"\&.
|
|
.RE
|
|
.SH "UNATTENDED MODE"
|
|
.sp
|
|
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\&.
|
|
.sp
|
|
This is not necessary when displaying the list, as the username and password are not required for read\-only mode\&.
|
|
.sp
|
|
Moreover, if you run this program inside a shell script or similar, you should only consider using output from stdout, not stderr\&.
|
|
.SH "DIAGNOSTICS"
|
|
.sp
|
|
\fBupsrw\fR can\(cqt set variables on your UPS unless you provide a valid username and password\&. If you get "access denied" errors, make sure that your \fBupsd.users\fR(5) has an entry for you, and that the username you are using has permissions to SET variables\&.
|
|
.SH "VALUE FORMAT"
|
|
.sp
|
|
When using \fBupsrw\fR to modify a numeric float value, that values must be given using decimal (base 10) english\-based representation, so using a dot, in non\-scientific notation\&. So hexadecimal, exponents, and comma for thousands separator are forbiden\&. For example: "1200\&.20" is valid, while "1,200\&.20" and "1200,20" are invalid\&.
|
|
.SH "HISTORY"
|
|
.sp
|
|
This program used to be called upsct2, which was ambiguous and confusing\&.
|
|
.SH "SEE ALSO"
