.SH DESCRIPTION
|
|
.B Swapon
|
|
is used to specify devices on which paging and swapping are to take place.
|
|
Calls to
|
|
.B swapon
|
|
normally occur in the system multi-user initialization file
|
|
.I /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:
|
|
.TP
|
|
.B \-a
|
|
All devices marked as ``sw'' swap devices in
|
|
.I /etc/fstab
|
|
are made available.
|
|
.PP
|
|
.B Swapoff
|
|
disables swapping on the specified devices and files, or on all swap
|
|
entries in
|
|
.I /etc/fstab
|
|
when the
|
|
.B \-a
|
|
flag is given.
