I have searched the web and forum and haven't found a straightforward answer to this question. I am adding programs to Precise Puppy but want to make sure I am staying less than the 500 MB I have for RAM. I am running Precise off of a USB Flash Drive. What is the easiest way to determine how much RAM my configuration of Puppy is utilizing? Thanks in advance.

If you are running your puppy, just type into the cosole:
Code:
free

Result here is:
Code:
sh-4.1# free
              total         used         free       shared      buffers
  Mem:      1554556      1498412        56144            0       380476
 Swap:      4157436            0      4157436
Total:      5711992      1498412      4213580
sh-4.1#

Second result here is, after flushing the RAM:
Code:
sh-4.1# free
              total         used         free       shared      buffers
  Mem:      1554556       572768       981788            0         2304
 Swap:      4157436            0      4157436
Total:      5711992       572768      5139224
sh-4.1#

To flush the RAM type into console (or create a bash script):
Code:
sync; echo 3 > /proc/sys/vm/drop_caches

The free command always confused me, since it reads in kilibites..

You can also make it read in Megabites use
Code:
free -m

I am running Lupu 520 and when I type "free -m" in a terminal, I get a busybox message of usage being only "free".
It evidently does not support the parameter in Lupu 520.

In Wary Puppy, I get the following:

Code:
# free
             total         used         free       shared      buffers
Mem:        385068       377792         7276            0        33912
-/+ buffers:             343880        41188
Swap:       396280            0       396280
# free -m
             total         used         free       shared      buffers
Mem:           376          366            9            0           33
-/+ buffers:                333           42
Swap:          386            0          386


I am assuming the apparent discrepancy with the values in kilobytes versus megabytes has to do with the algorithm that says: 1mb = 1024k

Sub_title: Hardinfo has tools to help		  
Cecil,

You might want to look at *Hardinfo* and some of the tools it offers.
