First - i wanted to know how many process are currently running so i used this command:
$ ps | wc
i was expecting to one number, but the output was:
20 115 844
Three numbers were printed - with a space in the size of 'tab' between them.
what are those numbers mean? are they somehow related to the different 'aux' i can use with ps? probably this is not one long number - that will mean my OS run over 20M process...
