# Free memory
pagesize=`pagesize`
kb_pagesize=`echo "scale=2; $pagesize/1024" | bc -l`
sar_freemem=`sar -r 1 1 | tail -1 | awk 'BEGIN {FS=" "} {print $2}'`
gb_freemem=`echo "scale=2; $kb_pagesize*$sar_freemem/1024/1024" | bc -l`

# Used Memory
gb_usedmem=`echo "scale=2; $gb_memory-$gb_freemem" | bc -l`

# Conclusion
echo "Avai Mem: $gb_memory GB"
echo "Free Mem: $gb_freemem GB"
echo "Used Mem: $gb_usedmem GB"
