41 .Nd display system data structures
54 displays open file entry, swap space utilization,
55 terminal state, and vnode data structures.
61 option is implied, and only the
65 The following options are available:
66 .Bl -tag -width indent
68 Print devices out by major/minor instead of name.
70 Print sizes in kilobytes, regardless of the setting of the
74 Print the number of used and free slots in several system tables.
75 This is useful for checking to see how large system tables have become
76 if the system is under heavy load.
78 Print the open file table with these headings:
79 .Bl -tag -width indent
81 The core location of this table entry.
83 The type of object the file table entry points to.
85 Miscellaneous state variables encoded thus:
87 .Bl -tag -width indent -compact
95 signal pgrp when data ready
98 Number of processes that know this open file.
100 Number of messages outstanding for this file.
102 The location of the vnode table entry or socket structure for this file.
108 Print information about swap space usage on all the
109 swap areas compiled into the kernel.
110 The first column is the device name of the partition. The next column is
111 the total space available in the partition. The
113 column indicates the total blocks used so far; the
115 column indicates how much space is remaining on each partition.
118 reports the percentage of space used.
120 If more than one partition is configured into the system, totals for all
121 of the statistics will be reported in the final line of the report.
123 If you supply the option again, as in
125 the system will display a breakdown of the swap bitmap/radix-tree.
127 Print table for terminals
129 .Bl -tag -width indent
131 Number of characters in raw input queue.
133 Number of characters in canonicalized input queue.
135 Number of characters in output queue.
140 Physical device address.
142 Number of delimiters (newlines) in canonicalized input queue.
144 Calculated column position of terminal.
146 Miscellaneous state variables encoded thus:
148 .Bl -tag -width indent -compact
150 delay timeout in progress
152 waiting for open to complete
156 outq has been flushed during DMA
164 process is waiting for space in output queue

170 output stopped (ixon flow control)
172 output stopped (carrier flow control)
174 output stopped (CTS flow control)
176 output stopped (DSR flow control)
180 send SIGIO for input events
190 next character is literal
192 retyping suspended input (PENDIN)
194 counting tab width, ignore FLUSHO
