Process memory usage


Hi - I am posting this here since it is such a basic question, altho' I do have experience with Linux.
I just want to get a listing of all running processes and the amount of memory used by each them. I cannot see that this is provided by ps, or by vmstat, or by top. There may be other utilities. I guess something a little along the lines of WIN Task Mgr, which gives precisely this info.
I apologize for the simplicity of this request, and maybe even ps does have that facility...that would indeed be the obvious command; I just can't find it.
Thanks
wombat

That's great. I presume the RSS is in KB?
Is MAN the best place to look for explanation of the column headers, or is there a better place?
Thanks
George

You should be aware that many memory-management algorithms are "lazy," never doing any more work than they have to unless, and until, genuine "memory pressure" occurs. Figures quoting memory-use may seem inflated.

ksysguard for example. Either ctrl+escape in KDE, look in the menu for 'KDE System Monitoring' or something or run ksysguard at a terminal.
