Title: Memory question
Post by: Andrew Hodgson on March 28, 2003, 11:18:50 PM

Hi,

This is a basic question for a Unix newby: How to check the available memory?  I am looking for similar to the mem command in Dos, though of course more detail would be nice :-)
Thanks,
Andrew.

http://www.justlinux.com/nhf/Command_Reference is very handy for us newbs. =)

Also, the PHPSysInfo contrib will show memory usage along with lots of other system info on a web page.

Do Alt F2 to switch to the 2nd terminal. Login as 'root'  
then type:

# mypc > dmesg |more |grep Memory

or without the '| grep Memory' for loads of good stuff!
This tells you about physical hardware.
Try 'top'  to see what is been used by what.

# mypc >top

And in both cases:
# mypc>man dmesg

and

# mypc>man top

will tell you all about these programs..
