MAC OSX turn on/disable Safesleep feature

If you want to disable, we need to enter the following command in the terminal:

　　sudo 0

Then navigate to/private/var/vm/to delete the already existing Sleepimage file

cd/private/var/vm/

Use the following command to delete the file

　　sudo RM Sleepimage

Finally we want to prevent OS X from continuing to create the file, so we need the following command to generate an empty file that cannot be replaced

　　Touch Sleepimage chmod  /private/var/vm/sleepimage

Of course, if you want to re-open the Safesleep function, just the following command.

　　sudo 3 sudo RM /private/var/vm/sleepimage　　

You can clean up a lot of hard disk space after disabling
