I have another query. I need to know how much ram installed on my CentOS 7 Linux server. I know in desktop it tells you easily. But, I need to check and see how mich RAM on Linux box. What command I type to see such information?
To check your RAM size on Linux box, use any one of the following command:
cat /proc/meminfo
OR
free -m
free -k

Another option is to run htop/top command:
top
htop
Or use https://www.cyberciti.biz/faq/ram-size-linux/
sudo dmidecode --type memory
