Dear friends,

Under linux free -m command works like a charm. What about UNIX system. there is not free command at all. How do i find out ram usage under UNIX (both HP-UX and Solari?

I'd appreciate if someone help me out, ASAP.

prtdiag | grep memory

Hi all,
prtconf & prtdiag | grep memory only gives the total memory allocated to system not the dynamic memory usage of the system which free -m gives on any Linux system which is best command.
vmstat gives the o/p in bytes.What is the option that would give o/p in Megabyte like free -m. ?

Appreciate anybody will clear this.

Thanks,

I know this is a somewhat dated thread, but I thought I [c-w]ould add to it in case somebody else needs the info:

I use the command:

Depending on which *nix you are running, it will show slightly different information; however, on AIX, openSUSE, Debian (et al), & BSD (the ones I'm familiar with atm), it will show total memory & used/available memory.

Hope that helps =)...
