Here’s how to view system memory on Linux.
Default display is in kB
cat /proc/meminfo MemTotal: 7492768 kB MemFree: 427368 kB MemAvailable: 5424768 kB |
cat /proc/meminfo MemTotal: 7492768 kB MemFree: 427368 kB MemAvailable: 5424768 kB
Display in MB
awk '$3=="kB"{$2=$2/1024;$3="MB"} 1' /proc/meminfo | column -t MemTotal: 7317.16 MB MemFree: 404.527 MB MemAvailable: 5285.4 MB |
awk '$3=="kB"{$2=$2/1024;$3="MB"} 1' /proc/meminfo | column -t MemTotal: 7317.16 MB MemFree: 404.527 MB MemAvailable: 5285.4 MB
Output in GB
awk '$3=="kB"{$2=$2/1024^2;$3="GB";} 1' /proc/meminfo | column -t MemTotal: 7.14566 GB MemFree: 0.370392 GB MemAvailable: 5.13733 GB |
