â†Created page with '==How to use it== The following ruby script can generates the following output ./battery.rb [+] 01:02 (90%) ./battery.rb -v The battery is charging Current Status 90...'

New page

==How to use it==
The following ruby script can generates the following output

./battery.rb
[+] 01:02 (90%)

./battery.rb -v
The battery is charging
Current Status 90%
Remaining Charging Time 01h02m
Charging Till 22:52

After 91 cycles the battery has 90% of its design capacity

./battery.rb -b
[######### ]

./battery.rb -h
This is a very small script for getting some usefull information about your battery
Please notice that this script requires tp_smapi which is only available on ThinkPads

Version 0.1 written by futejia during the 24C3 in Berlin
The script is published under the 'Beer License' which means you can do whatever you want, and when you like the script you buy me a beer

Command line options:
All information you usually need in one single line
-h Prints this help
-b Prints a nice ascii battery (Single line)
-v Gives some more information about the battery

==The script itself==
Simple safe this as battery.rb (Of course you need ruby and tp_smapi installed)
