How do you empty you swap memory on Redhat or Fedora Linux

If you want to clear out your swap you can use the following commands.

#free

              total        used        free      shared  buff/cache   available
Mem:       16266516     5208028     8793132       96412     2265356    10509976
Swap:       8269820           10000    8259820


Then we use this command to disable swap:
$ swapoff -a




 


You can confirm that it's now empty: 


 

#free



              total        used        free      shared  buff/cache   available

Mem:       16266516     5208028     8793132       96412     2265356    10509976

Swap:       8269820                  0      8269820 


 



we  re-enable our swap:


#swapon -a
