the very reason i started with linux, the very reason im still with linux, is that there is something to learn, teh chalenge, and the satisfaction of personal growth.
"moving to perl" doesn't mean anything "bad"
i will finish this with bash (because i wont let this sucker win). and after that, i will try to make it in perl. just because i can (or rather "just because i still dont know how" )

there is only one more thing i want from this script. show the total of memory used, and the total of cpu used, while keeping it light

for the cpu. i had some doubts, but i have decided to show the iddle percentage. this is a personal thing, i will use it, so if i want/know iddle%, thats what im gonna get :P

for the memory, i have been researching.
i was using wmmem, so i went and read the code to and read how it calculated. i came up with the math behind it.
((total - cache - buffer) * 100 ) / total
now my problem is getting those 3 from top

unfortunately, all my work is in my personal laptop (at home), and usually, i dont spent time in this during the week, so i cant give you any particulars on what i have done so far to retrieve that data
i dont ask you to rewrite my script. actually i would hate that.
as i said, i want to solve this, or at least try

thanks for the great help so far !

I3BAR(1)																  I3BAR(1)

NAME
i3bar - xcb-based status- and workspace-bar SYNOPSIS
i3bar [-s sock_path] [-b bar_id] [-v] [-h] WARNING
i3bar will automatically be invoked by i3 for every bar configuration block. Starting it manually is usually not what you want to do. You have been warned! OPTIONS
-s, --socket sock_path Overwrites the path to the i3 IPC socket. -b, --bar_id bar_id Specifies the bar ID for which to get the configuration from i3. -v, --version Display version number and exit. -h, --help Display a short help-message and exit DESCRIPTION
i3bar displays a bar at the bottom (or top) of your monitor(s) containing workspace switching buttons and a statusline generated by i3status(1) or similar. It is automatically invoked (and configured through) i3. i3bar does not support any color or other markups, so stdin should be plain utf8, one line at a time. If you use i3status(1), you therefore should specify output_format = none in the general section of its config file. ENVIRONMENT
I3SOCK Used as a fallback for the i3 IPC socket path if neither the commandline contains an argument nor the I3_SOCKET_PATH property is set on the X11 root window. EXAMPLES
Nothing to see here, move along. As stated above, you should not run i3bar manually. Instead, see the i3 documentation, especially the User's Guide. SEE ALSO
i3status(1) or conky(1) for programs generating a statusline. dzen2(1) or xmobar(1) for similar programs to i3bar. AUTHORS
