Linux free memory

  
                  

Although Linux will automatically release memory, but sometimes. . . You can manually release it with the following command. In fact, as long as the first command and the last command are OK, but I am not called boring, so the settings are run again

sync echo 1 > /proc/sys/Vm/drop_caches echo 2 > /proc/sys/vm/drop_caches echo 3 > /proc/sys/vm/drop_caches
