| 8 | .Nd display free swap space | |
| 9 | .Sh SYNOPSIS | |
| 10 | .Nm swapinfo | |
| 11 | .Op Fl k | |
| 12 | .Sh DESCRIPTION | |
| 13 | .Nm Swapinfo | |
| 14 | displays statistics about the amount of free swap space on all of the | |
| 15 | swap areas compiled into the kernel. | |
| 16 | .Pp | |
| 17 | The following options are available: | |
| 18 | .Bl -tag -width Ds | |
| 19 | .It Fl k | |
| 20 | By default, all sizes are reported in 512-byte block counts. | |
| 21 | The | |
| 22 | .Fl k | |
| 23 | option causes the numbers to be reported in kilobyte counts. | |
| 24 | .El | |
| 25 | .Sh STATISTICS | |
| 26 | Statistics are reported for all swap partitions configured into the kernel. | |
| 27 | The first column is the device name of the partition. The next column is | |
| 28 | the total space available in the partition. The | |
| 29 | .Ar Used | |
| 30 | column indicates the total blocks used so far; the | |
| 31 | .Ar Available | |
| 32 | column indicates how much space is remaining on each partition. | |
| 33 | The | |
| 34 | .Ar Capacity | |
| 35 | reports the percentage of space used. | |
| 36 | .Pp | |
| 37 | If more than one partition is configured into the system, totals for all | |
| 38 | of the statistics will be reported in the final line of the report. | |
| 39 | .Sh "BUGS AND CAVEATS" | |
| 40 | The information reported by | |
| 41 | .Nm swapinfo | |
| 42 | is stored in the kernel in a linked list. Since we are merely reading | |
| 43 | this list out of kernel memory, it is entirely possible that the list could | |
| 44 | change as we try to read it. Suspicious and unrepeatable values are probably | |
| 45 | incorrect. | |
| 46 | .Pp | |
| 47 | Statistics are reported for all swap partitions compiled into the kernel, | |
| 48 | regardless of whether those partitions are being used. | |
