To find out the memory (RAM) size information on an OpenBSD system, you can use the dmesg command, which displays system boot messages and other kernel information.
To display memory size information, open a terminal window and type the following command:
dmesg | grep memory
This will display information about the amount of RAM installed in your system. The output will look something like this:
real mem = 8589934592 (8192MB)
avail mem = 8335503872 (7942MB)
In this example, the system has 8 GB of installed RAM.
You can also use the top command to view system information, including memory usage. To display memory information using top, open a terminal window and type the following command:
top
This will display a list of running processes, along with information about memory usage. Look for the “Memory” section at the top of the screen to view total and free memory information.
You can exit top by pressing the “q” key.
