how many users?

[Bruce Easton]

Top-post:

Overly-expensive for me is when I have to remember different flags for 
diff. versions of *nixes.  I suppose that's why my initial response on 
this had "ps -ef".  Granted egrep is better suited for the regex, but if 
I know something simpler to key on one command line, and perhaps easier 
to read by others, I gravitate towards it, which is why I went the "grep 
-e xxx -e yyy -e zzz" route.  In any case, I surely could use more memory :)


Also, as I stated in the follow-up to my initial response, be aware that 
including "grep -v grep" could lead to undesired results if there is the 
likelihood of a filepro file/format name containing "grep".  Including 
more of the command should make it safer since it would be unlikely for 
an fp call:
grep -v "grep -e"
