If you want to get the free Ram of your system you could run:
|
1 |
free | awk "NR == 2" | awk '{print $4}' |
this return free ram in gigabytes :
|
1 |
free -g | awk "NR == 2" | awk '{print $4}' |
Check if the value is right :
|
1 |
free;free | awk "NR == 2" | awk '{print $4}' |
result :
total used free shared buffers cached
Mem: 7573696 6918704 654992 0 362128 5550592
-/+ buffers/cache: 1005984 6567712
Swap: 2540540 480 2540060
654216
seems fine.
