.Sh SYNOPSIS
|

|
.Nm swapinfo
|
||
|
.Op Fl k
|
||
|
.Sh DESCRIPTION
|
||
|
.Nm Swapinfo
|
||
|
displays statistics about the amount of free swap space on all of the
|
||
|
swap areas compiled into the kernel.
|
||
|
.Pp
|
||
|
The following options are available:
|
||
|
.Bl -tag -width Ds
|
||
|
.It Fl k
|
||
|
By default, all sizes are reported in 512-byte block counts.
|
||
|
The
|
||
|
.Fl k
|
||
|
option causes the numbers to be reported in kilobyte counts.
|
||
|
.El
|
||
|
.Sh STATISTICS
|
||
|
Statistics are reported for all swap partitions configured into the kernel.
|
||
|
The first column is the device name of the partition. The next column is
|
||
|
the total space available in the partition. The
|
||
|
.Ar Used
|
||
|
column indicates the total blocks used so far; the
|
||
|
.Ar Available
|
||
|
column indicates how much space is remaining on each partition.
|
||
|
The
|
||
|
.Ar Capacity
|
||
|
reports the percentage of space used.
|
||
|
.Pp
|
||
|
If more than one partition is configured into the system, totals for all
|
||
|
of the statistics will be reported in the final line of the report.
|
||
|
.Sh "BUGS AND CAVEATS"
|
||
|
The information reported by
|
||
|
.Nm swapinfo
|
||
|
is stored in the kernel in a linked list. Since we are merely reading
|
||
|
this list out of kernel memory, it is entirely possible that the list could
|
||
|
change as we try to read it. Suspicious and unrepeatable values are probably
|
||
|
incorrect.
|
||
|
.Pp
|
||
|
Statistics are reported for all swap partitions compiled into the kernel,
|
||
|
regardless of whether those partitions are being used.
