Measure the memory

the command free will show you the free memory in the system

vagrant@vagrant-ubuntu-trusty-64:~$ whatis free
free (1)             - Display amount of free and used memory in the system

and with the flag --si and -h you can get a better representation, --si will show you GigaBytes instead Gigibytes and the flag -h include the symbols

vagrant@vagrant-ubuntu-trusty-64:~$ free --si -h
             total       used       free     shared    buffers     cached
Mem:          501M       205M       295M       372K        18M        72M
