How to check physical RAM size with Redhat

Tuesday, September 11th, 2012

Company acquisitions always create “fun” when it comes to incorporating their usable equipment into the network.  The question of RAM will always get asked as small companies don’t always purchase large amounts of RAM for workstations and servers.

If you have a Redhat system and need to know the amount of physical ram, you can always look at meminfo.

Simply log into the system in question and enter : cat /proc/meminfo

The first two lines will answer your memory questions.

$ cat /proc/meminfo
