DESCRIPTION

If invoked as swapinfo the -s option is implied, and only the -h, -k, -m, -g, -M and -N options are legal.

The following options are available:

-n

Print devices out by major/minor instead of name.

-h

Print sizes with human-readable scaling. BLOCKSIZE is ignored.

-k

Print sizes in kilobytes, regardless of the setting of the BLOCKSIZE environment variable.

-m

Print sizes in megabytes, regardless of the setting of the BLOCKSIZE environment variable.

-g

Print sizes in gigabytes, regardless of the setting of the BLOCKSIZE environment variable.

-T

Print the number of used and free slots in several system tables. This is useful for checking to see how large system tables have become if the system is under heavy load.

-f

Print the open file table with these headings:

LOC

The core location of this table entry.

TYPE

The type of object the file table entry points to.

FLG

Miscellaneous state variables encoded thus:

R

open for reading

W

open for writing

A

open for appending

S

shared lock present

X

exclusive lock present

I

signal pgrp when data ready

CNT

Number of processes that know this open file.

MSG

Number of messages outstanding for this file.

DATA

The location of the vnode table entry or socket structure for this file.

OFFSET

The file offset (see lseek(2)).

-s

Print information about swap space usage on all the swap areas compiled 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 Used column indicates the total blocks used so far; the Available column indicates how much space is remaining on each partition. The Capacity reports the percentage of space used.

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.

If you supply the option again, as in -ss, the system will display a breakdown of the swap bitmap/radix-tree.

-t

Print table for terminals with these headings:

RAW

Number of characters in raw input queue.

CAN

Number of characters in canonicalized input queue.

OUT

Number of characters in output queue.

MODE

See tty(4).

ADDR

Physical device address.

DEL

Number of delimiters (newlines) in canonicalized input queue.

COL

Calculated column position of terminal.

STATE

Miscellaneous state variables encoded thus:

T

delay timeout in progress

W

waiting for open to complete

O

open

F

outq has been flushed during DMA

C

carrier is on

c

connection open

B

busy doing output

A

process is waiting for space in output queue

a

process is waiting for output to complete

X

open for exclusive use

S

output stopped (ixon flow control)

m

output stopped (carrier flow control)

o

output stopped (CTS flow control)

d

output stopped (DSR flow control)

K

input stopped

Y

send SIGIO for input events

D

state for lowercase ‘\’ work

E

within a ‘\.../’ for PRTRUB

L

next character is literal

P

retyping suspended input (PENDIN)

N

counting tab width, ignore FLUSHO

l

block mode input routine in use

s

i/o being snooped

Z

connection lost

SESS

Kernel address of the session structure.

PGID

Process group for which this is controlling terminal.

DISC

Line discipline; ‘term’ for TTYDISC or ‘ntty’ for NTTYDISC or ‘tab’ for TABLDISC or ‘slip’ for SLIPDISC or ‘ppp’ for PPPDISC.

-M

Extract values associated with the name list from the specified core instead of the default /dev/kmem.

-N

Extract the name list from the specified system instead of the default /boot/kernel.
