It should be displayed early in the dmesg(8) output shown during the
boot process. You may review this by executing the dmesg(8) command.
Among the output will be listed:
dmesg | grep "memory"
real memory = 2146304000 (2046 MB)
avail memory = 2087034880 (1990 MB)
You could also check the appropriate sysctl(8) variables as follows:
sysctl hw.physmem
sysctl hw.usermem
sysctl hw.realmem
To get memory usage statistics you can use ps(1) and top(1):
ps -u
top
