SWAPON(8)

NAME
swapon, swapoff - enable/disable devices and files for paging and swapping

SYNOPSIS
/sbin/swapon -a
/sbin/swapon specialfile ...
/sbin/swapoff -a
/sbin/swapoff specialfile ...

DESCRIPTION
Swapon is used to specify devices on which paging and swapping are to take place. Calls to swapon normally occur in the system multi-user initialization file /etc/rc making all swap devices available, so that the paging and swapping activity is interleaved across several devices and files. Normally, the first form is used:

-a  All devices marked as ``sw'' swap devices in /etc/fstab are made available.

Swapoff disables swapping on the specified devices and files, or on all swap entries in /etc/fstab when the -a flag is given.
