I wanted to know how the 'SIZE' field in the output of 'top' command is
calculated in linux.

well, if i remember correctly the size field in ps results in process size in clicks. one click is 4096 bytes. it's pretty good for relative measurement (e.g. this one is 50 clicks, the other one is 5000 clicks).

let's see about 'top'. reading man page

SIZE The size of the task's code plus data plus stack
space, in kilobytes, is shown here.

so, it sounds like kb. in addition, you might find these fields helpful too (from the man page).

TSIZE The code size of the task. This gives strange
values for kernel processes and is broken for ELF processes.

DSIZE Data + Stack size. This is broken for ELF
processes.

Hi mark ,

Thanks for the info.

But the question really is , whether SIZE corrosponds to

real memory( real text + real data + real stack)
OR
virtual memory(virtual text + virtual data + virtual stack)
OR
both????

Thanks
Milind
