The following options are available:
| |
Print devices out by major/minor instead of name. | |
| |
"Human-readable" output. Use unit suffixes when printing swap partition sizes: Byte, Kilobyte, Megabyte, Gigabyte, Terabyte and Petabyte. | |
| |
Print sizes in kilobytes, regardless of the setting of the BLOCKSIZE environment variable. | |
| |
Print sizes in megabytes, regardless of the setting of the BLOCKSIZE environment variable. | |
| |
Print sizes in gigabytes, regardless of the setting of the BLOCKSIZE environment variable. | |
| |
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. | |
| |
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 |
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)). | |
| |
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. | |
| |
Print table for terminals with these headings: | |
LINE | Device name. |
INQ | Number of characters that can be stored in the input queue. |
CAN | Number of characters in the input queue which can be read. |
LIN | Number of characters in the input queue which cannot be read yet. |
LOW | Low water mark for input. |
OUTQ | Number of characters that can be stored in the output queue. |
USE | Number of bytes in the output queue. |
LOW | Low water mark for output. |
COL | Calculated column position of terminal. |
SESS | Process ID of the session leader. |
PGID | Process group for which this is the controlling terminal. |
STATE |
Miscellaneous state variables encoded thus:
|
I | init/lock-state device nodes present |
C | callout device nodes present |
O | opened |
c | console in use |
G | gone |
B | busy in open(2) |
Y | send SIGIO for input events |
L | next character is literal |
H | high watermark reached |
X | open for exclusive use |
S | output stopped (ixon flow control) |
l | block mode input routine in use |
Z | connection lost |
s | i/o being snooped |
b | busy in read(2) or write(2) |
The ‘i’ and ‘o’ characters refer to the previous character, to differentiate between input and output.
| |
Extract values associated with the name list from the specified core. | |
