Looking for direction with reagarding a top/htop like app
 

Hey All,

I write alot of generalized scripts for watching processes, cpu/mem usage etc...

I am looking at writing an app that posts new data to the screen, similar to top or htop. Mainly i am after how you get the "static" looking screen and just update that as needed.

Not looking for code, but if anyone can point me in the right direction on google, i would greatly appreciate it.

If my question is too vague, please let me know.

Thanks,

Hello,

Usually people use "curses" for that.
You can watch the source code of some applications that use it to get detailed examples.
Usually its used in C programs but there are bindings to other languages (I know iotop uses it in python for example).

But you can do it 'as well' in a shell script although it might be somewhat slow, but if it's only for a little script of your own, why not. In that case, tput can help you. An small example :
you can read the man page to get some extra information.

Hope this helps.

Hey,

Thanks for the info, I am open to other languages for this app, kinda started with shell at random.
I will check into tput as well some python or c and see what i can dig up.

Thanks much. :)
