Linux: What is the best way to estimate the code & static data size of program?

Question

I want to be able to get an estimate of how much code & static data is used by my C++ program?

Is there a way to find this out by looking at the executable or object files? Or perhaps something I can do at runtime?

Will objdump & readelf help?

Answer 1

"size" is the traditional tool. "readelf" has a lot of options.

$ size /bin/sh
   text    data     bss     dec     hex filename
 712739   37524   21832  772095   bc7ff /bin/sh
