48 .Nd display system data structures
62 utility displays open file entry, swap space utilization,
63 terminal state, and vnode data structures.
69 option is implied, and only the
73 The following options are available:
74 .Bl -tag -width indent
76 Print devices out by major/minor instead of name.
78 Print sizes in kilobytes, regardless of the setting of the
82 Print the number of used and free slots in several system tables.
83 This is useful for checking to see how large system tables have become
84 if the system is under heavy load.
86 Print the open file table with these headings:
87 .Bl -tag -width indent
89 The core location of this table entry.
91 The type of object the file table entry points to.
93 Miscellaneous state variables encoded thus:
95 .Bl -tag -width indent -compact
103 signal pgrp when data ready
106 Number of processes that know this open file.
108 Number of messages outstanding for this file.
110 The location of the vnode table entry or socket structure for this file.
116 Print information about swap space usage on all the
117 swap areas compiled into the kernel.
118 The first column is the device name of the partition. The next column is
119 the total space available in the partition. The
121 column indicates the total blocks used so far; the
123 column indicates how much space is remaining on each partition.
126 reports the percentage of space used.
128 If more than one partition is configured into the system, totals for all
129 of the statistics will be reported in the final line of the report.
131 If you supply the option again, as in
133 the system will display a breakdown of the swap bitmap/radix-tree.
135 Print table for terminals
137 .Bl -tag -width indent
139 Number of characters in raw input queue.
141 Number of characters in canonicalized input queue.
143 Number of characters in output queue.
148 Physical device address.
150 Number of delimiters (newlines) in canonicalized input queue.
152 Calculated column position of terminal.
154 Miscellaneous state variables encoded thus:
156 .Bl -tag -width indent -compact
158 delay timeout in progress
160 waiting for open to complete
164 outq has been flushed during DMA
172 process is waiting for space in output queue
174 process is waiting for output to complete
176 open for exclusive use
178 output stopped (ixon flow control)
180 output stopped (carrier flow control)
182 output stopped (CTS flow control)
184 output stopped (DSR flow control)
188 send SIGIO for input events
198 next character is literal
200 retyping suspended input (PENDIN)
202 counting tab width, ignore FLUSHO
204 block mode input routine in use
211 Kernel address of the session structure.
