how to find out what serivces/process are running in fedora
 

How to find out what serivces/process are running in fedora thru command line?

And if there is a way to find out which processes use up the memory of the machine thru command line?

Thank you.

Try running "top". Or you can run "ps -aux | less" to display other useful information.

Try ps or ps -A for a process list.
Try top for a screen (refreshed every few seconds) to the processes using the "top" amount resources.

Append a --help option for a syntax list, and man ps (or man top) for more info.

Also man -K <topic> will list available commands with <topic> in their keyword lists, an info --apropos <topic> will do a similar search of the info files.
