37 .Nd display system data structures
50 displays open file entry, swap space utilization,
51 terminal state, and vnode data structures.
57 option is implied, and only the
63 The following options are available:
64 .Bl -tag -width indent
66 Print devices out by major/minor instead of name.
68 Print sizes with human-readable scaling.
72 Print sizes in kilobytes, regardless of the setting of the
76 Print sizes in megabytes, regardless of the setting of the
80 Print sizes in gigabytes, regardless of the setting of the
84 Print the number of used and free slots in several system tables.
85 This is useful for checking to see how large system tables have become
86 if the system is under heavy load.
88 Print the open file table with these headings:
89 .Bl -tag -width indent
91 The core location of this table entry.
93 The type of object the file table entry points to.
95 Miscellaneous state variables encoded thus:
97 .Bl -tag -width indent -compact
107 exclusive lock present
109 signal pgrp when data ready
112 Number of processes that know this open file.
114 Number of messages outstanding for this file.
116 The location of the vnode table entry or socket structure for this file.
122 Print information about swap space usage on all the
123 swap areas compiled into the kernel.
124 The first column is the device name of the partition. The next column is
125 the total space available in the partition. The
127 column indicates the total blocks used so far; the
129 column indicates how much space is remaining on each partition.
132 reports the percentage of space used.
134 If more than one partition is configured into the system, totals for all
135 of the statistics will be reported in the final line of the report.
137 If you supply the option again, as in
139 the system will display a breakdown of the swap bitmap/radix-tree.
141 Print table for terminals
143 .Bl -tag -width indent
145 Number of characters in raw input queue.
147 Number of characters in canonicalized input queue.
149 Number of characters in output queue.
154 Physical device address.
156 Number of delimiters (newlines) in canonicalized input queue.
158 Calculated column position of terminal.
160 Miscellaneous state variables encoded thus:
162 .Bl -tag -width indent -compact
164 delay timeout in progress
166 waiting for open to complete
170 outq has been flushed during DMA
178 process is waiting for space in output queue
180 process is waiting for output to complete
182 open for exclusive use
184 output stopped (ixon flow control)
186 output stopped (carrier flow control)
188 output stopped (CTS flow control)
190 output stopped (DSR flow control)
206 next character is literal
208 retyping suspended input (PENDIN)
210 counting tab width, ignore FLUSHO
212 block mode input routine in use
219 Kernel address of the session structure.
221 Process group for which this is controlling terminal.
245 Extract values associated with the name list from the specified core
246 instead of the default
249 Extract the name list from the specified system instead of the default
253 .Bl -tag -width /dev/memxxx -compact
257 default source of tables
