42 .Nd display system data structures
55 displays open file entry, swap space utilization,
56 terminal state, and vnode data structures.
62 option is implied, and only the
66 The following options are available:
67 .Bl -tag -width indent
69 Print devices out by major/minor instead of name.
71 Print sizes in kilobytes, regardless of the setting of the
75 Print the number of used and free slots in several system tables.
76 This is useful for checking to see how large system tables have become
77 if the system is under heavy load.
79 Print the open file table with these headings:
80 .Bl -tag -width indent
82 The core location of this table entry.
84 The type of object the file table entry points to.
86 Miscellaneous state variables encoded thus:
88 .Bl -tag -width indent -compact
98 exclusive lock present
100 signal pgrp when data ready
103 Number of processes that know this open file.
105 Number of messages outstanding for this file.
107 The location of the vnode table entry or socket structure for this file.
113 Print information about swap space usage on all the
114 swap areas compiled into the kernel.
115 The first column is the device name of the partition. The next column is
116 the total space available in the partition. The
118 column indicates the total blocks used so far; the
120 column indicates how much space is remaining on each partition.
123 reports the percentage of space used.
125 If more than one partition is configured into the system, totals for all
126 of the statistics will be reported in the final line of the report.
128 If you supply the option again, as in
130 the system will display a breakdown of the swap bitmap/radix-tree.
132 Print table for terminals
134 .Bl -tag -width indent
136 Number of characters in raw input queue.
138 Number of characters in canonicalized input queue.
140 Number of characters in output queue.
145 Physical device address.
147 Number of delimiters (newlines) in canonicalized input queue.
149 Calculated column position of terminal.
151 Miscellaneous state variables encoded thus:
153 .Bl -tag -width indent -compact
155 delay timeout in progress
157 waiting for open to complete
161 outq has been flushed during DMA
169 process is waiting for space in output queue
171 process is waiting for output to complete
173 open for exclusive use
175 output stopped (ixon flow control)
177 output stopped (carrier flow control)
179 output stopped (CTS flow control)
181 output stopped (DSR flow control)
197 next character is literal
199 retyping suspended input (PENDIN)
201 counting tab width, ignore FLUSHO
203 block mode input routine in use
210 Kernel address of the session structure.
212 Process group for which this is controlling terminal.
236 Extract values associated with the name list from the specified core
237 instead of the default
240 Extract the name list from the specified system instead of the default
244 .Bl -tag -width /dev/memxxx -compact
248 default source of tables
