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 !

Dzen is a general-purpose messaging and notification program for X11, desigend to be scriptable in any language and integrate well with window managers like dwm, wmii and xmonad though it will work with any windowmanger.

See README for detailed usage and scripting instructions. OPTIONS

The <color> can be specified either as symbolic name (e.g. red, darkgreen, etc.) or as #rrggbb hex-value (e.g. #ffffaa). -bg <color> Set background color (same format as -fg). -fn <font> Set font (using the format of xlsfonts and xfontsel). -ta <l|c|r> Set alignement of title window content: l(eft), c(center) or r(ight). -tw <pixels> Set title window width. -sa <l|c|r> Set alignment of slave window (see -ta ). -l <lines> Number of lines to display in slave window (see (1) in README). -e <event1=action1:option1:...,action2;event2=...> Set up events and actions, eg. responses to mouse clicks (see (2) in README). -m Start up in menu mode (see (3) in README). -u Update contents of title and slave window simultaneously, see (see (4) in README). -p [<timeout>] Persist EOF (optional timeout in seconds). -x <pixels> Set x position on the screen. -y <pixels> Set y position on the screen. -h <pixels> Set line height (defaults to fontheight + 2 pixels). -w <pixels> width -xs <n> Set the Xinerama screen number where dzen should appear. -v Display version information.
