Display RAM Size on windows
check the ram size on windows platform with systeminfo or wmic commands
systeminfo |find "Total Physical Memory"

Display RAM Size on DEC-UNIX
In DEC-UNIX, you can use the uerf command in conjunction with grep to display memory size. For example:
uerf -r 300 | grep -i mem
Here, the output of the uerf command is piped to grep to filter out and display the segments relating to memory.
The –i option causes grep to find both uppercase and lowercase strings. With respect to the example shown here, grep –i mem looks for both “MEM” and “mem.”
Display RAM Size on HP/UX
In HP/UX, the dmesg command can display memory information:
physical page size = 4096 bytes, logical page size = 4096 bytes
Physical: 5242880 Kbytes,lockable: 4051216 Kbytes,available: 4651796 Kbytes
Display RAM Size on AIX
In IBM’s AIX , you must issue two separate commands. You start with the lsdev command followed by the lsattr command to display the amount of memory on a server.
First, execute lsdev to list all devices. Then pipe that output through grep to filter out everything not related to memory.
That will get you the name of the memory devices that are installed. For example:
lsdev -C|grep mem
mem0 Available 00-00 Memory
Here you can see that mem0 is the name of the memory device. Now that you have the name,
you can issue the lsattr –El command to see the amount of memory on the server.
In the following example, the server has 3GB of RAM installed.
lsattr -El mem0
size 3064 Total amount of physical memory …
You must issue the lsattr –El command separately for each memory device.
Display RAM Size on Solaris
The prtconf command can also be used on all Solaris servers to quickly see the amount of available memory:
prtconf|grep -i mem
Memory size: 2048 Megabytes
memory (driver not attached)
virtual-memory (driver not attached)
Display RAM Size in Linux
In Linux, the free command can be used to quickly display the amount of RAM memory on the server:
total used free shared buffers cached
Mem: 3728668 504688 3223980 41316 430072 29440
-/+ buffers/cache: 45176 3683492
