sorryyyy !!

thanks alot

I’ve followed this to a tee and still I only get a display of:

[battery]

Nothing more. I’m not sure what I did wrong. I made the file correctly, copied the code correctly, and changed the path correctly. I’m stumped! Can you please email me as I do not check this post often. Thanks!

Matt or Paul one question please :

I implemented the script of Matt but i not the percentage of the battery that appears ?

Thanks for help

Best regard

Third time is a charm, right?

Cheers,
/Paul

I just thought to check the console for errors and noticed a few.. that’s why I noticed the first error and then this one. Sorry. Feel free to delete all of these comments and just put the final, working script online… or edit as you feel fit.

Cheers
/Paul

I’m not sure if this is going to embed in the comment correctly, but this is what I came up with after tweaking yours a little. A few notes:

* I’ve never seen, let alone written, shell scripting, so I’m sure this is really poor. I would love input.
* Mine is calculating health based on a fixed number in the script. 5500, I think, is the original capacity of my MBP’s battery.
* I created a cute little battery display. $starcount_size lets you customize how wide the display is.

Thanks for your original!!!

Thanks again!

This is the new script (even updated in the main post):

#!/bin/bash
 
maxcap=`ioreg -l | grep Capacity |awk '/MaxCapacity/{print $5}'`
curcap=`ioreg -l | grep Capacity |awk '/CurrentCapacity/{print $5}'`
 
curcap=`echo $curcap*1000|bc`
proc=`echo $curcap / $maxcap |bc`;
 
len=`echo ${#proc}`;
 
proc_num=${proc:0:3}
proc_dec=${proc:3:4}
 
proc_num_len=`echo ${#proc_num}`;
 
if [ $proc_num_len == "3" ]; then
        if [ $proc_num != "100" ]; then
                proc_num=${proc:0:2}
                proc_dec=${proc:2:3}
        fi
fi
 
echo $proc_num.$proc_dec%
