Type "man awk" in the terminal for a full description of the command.
If max is not greater than zero, then something wrong happened (maybe ioreg doesn't have a line which says "MaxCapacity") and so return the character "?". Chemistry 2015 board paper sem 1, Kawasaki brute force battery operated, Caporales 2012 urcos. If the variable max is greater than zero, then take the contents of the array labelled "CurrentCapacity", divide it by max, and multiply by 100. Next it prints out the result of the formula max>0?100*c/max:"?"which is an if-then statement (with the form test?true:false awk stole this notation from C). Second, it defines the variable max to be the contents of the array labelled "MaxCapacity" (which was defined in the first part of the process). First it sets OFMT="%.2f%%", which means to change the output format so that it outputs real numbers with two decimal places followed by a percentage sign (as above). The END segment means to run the following command after you're done reading in standard input. (Unlike in some languages, awk's arrays can be labelled with text, not just numbers.) Whenever column 3 ($3) contains the word "Capacity" ($3~/Capacity), it runs the command "c=$5", which stores the fifth column into an array (a box) labelled with the contents of the third column. This awk command starts by reading in each line of ioreg -l, one at a time.

The printf command calculates $10/$5*100 (that is, the 10th column divided by the 5th column, times 100) and prints it as a floating-point number with 2 decimal places ("%.2f") followed by a percentage sign ("%%").Īwk '$3~/Capacity/ ' To check the battery level of your compatible Bluetooth devices on Windows 10, use these steps: 1 Open Settings. (So $5 is the 5th column's data and $10 is the 10th column's). Hsphfpd reports battery status (and other stuff) through DBus, so to get it from the command line, you can just do dbus-send -system -dest=org.hsphfpd -print-reply /org/hsphfpd/hci0/dev_XX_XX_XX_XX_XX_XX/hsp_hs .Get string: string:BatteryLevelīoth of these are available in the AUR, if you use Arch Linux.This first awk command reads the standard input, one line at a time (if necessary I'm guessing only one line is being sent to it here), and splits the line into columns, the data in column c having the name $c. Or you can right-click Start and select Settings from the menu that pops up. Even though these are both still prototypes, they seem to work very well. First, open Windows Settings by pressing Windows+i on your keyboard. There is a version of PulseAudio patched to use hsphfpd. That way, PulseAudio and whatever can both use the headset at the same time. Hsphfpd is specification with some prototype implementation used for connectingīluetooth devices with HSP and HFP profiles on Linux operating system.īasically, since only one program can communicate with the headset at once and it wouldn't make sense to implement battery level reporting in an audio server, nor implement audio in a power management software, it moves that functionality to an external daemon. Only one program can open a socket to talk to the bluetooth device, so it ends up fighting with PulseAudio over it. If I understand the problem correctly, that happens because I'd been using the Python program from clst's answer for some time and although it worked, it required me to connect, then disconnect and run it again.
