This manual page documents briefly the wmacpi command.
wmacpi is a program that displays the current battery status in a WindowMaker dock app, on
systems that support Intel's Advanced Configuration and Power Interface specification
The program monitors a battery, displaying its current percentage charge via a bar and a
numeric value. It also displays the current power status for the system, the time
remaining (calculated based on the remaining battery capacity and the current rate of
power usage), and a scrolling message with some hopefully useful information.
Clicking on the window cycles through the batteries that the ACPI system knows about.
wmacpi-cli queries the battery status from the command line. It prints the power status,
the percentage remaining for each battery found, and the time remaining if the system is
on battery, or the time remaining for each battery to reach full charge if the batteries
Set critical low alarm at <percentage>% (default: 10%).
Set the X display to open the window on.
-m, --battery=battery number
Set the battery to monitor initially.
-s, --sample-rate=sample rate
Set the rate at which to sample the ACPI data, in number of times per minute.
Minimum is 1, ie once a minute, default is 20, maximum is 600.
Disable blinking power glyph when charging. Note that it still blinks when the
battery reports its capacity state as critical.
Force the use of capacity mode for calculating time remaining. By defalt wmacpi
will use the reported values of remaining capacity and present rate to calculate
the time remaining on battery. This flag will force the use of the remaining
capacity and time samples to calculate the present rate of drain, and from there
the time remaining. Note that this mode of calculation generally underreports the
time remaining. This mode works around certain buggy ACPI BIOSes that fail to
report the current rate.
Run wmacpi in command line mode - this operates identically to wmacpi-cli.
Average the time remaining over num samples. This greatly improves the accuracy of
the reported time remaining.
Increase the verbosity of the program. Setting this to 1 will print extra error
information; 2 will produce informational output; 3 will produce copious debugging
Print the version information.
Disable scrolling message.
-a num Average the time remaining over num samples. This greatly improves the accuracy of
the reported time remaining.
-V Increase the verbosity of the program. If repeated, the result is the same as
setting --verbosity for wmacpi to the number of repetitions.
-v Print the version information.
-h Display help.
