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
97 exclusive lock present
99 signal pgrp when data ready
102 Number of processes that know this open file.
104 Number of messages outstanding for this file.
106 The location of the vnode table entry or socket structure for this file.
112 Print information about swap space usage on all the
113 swap areas compiled into the kernel.
114 The first column is the device name of the partition. The next column is
115 the total space available in the partition. The
117 column indicates the total blocks used so far; the
119 column indicates how much space is remaining on each partition.
122 reports the percentage of space used.
124 If more than one partition is configured into the system, totals for all
125 of the statistics will be reported in the final line of the report.
127 If you supply the option again, as in
129 the system will display a breakdown of the swap bitmap/radix-tree.
131 Print table for terminals
133 .Bl -tag -width indent
135 Number of characters in raw input queue.
137 Number of characters in canonicalized input queue.
139 Number of characters in output queue.
144 Physical device address.
146 Number of delimiters (newlines) in canonicalized input queue.
148 Calculated column position of terminal.
150 Miscellaneous state variables encoded thus:
152 .Bl -tag -width indent -compact
154 delay timeout in progress
156 waiting for open to complete
160 outq has been flushed during DMA
168 process is waiting for space in output queue
170 process is waiting for output to complete
172 open for exclusive use
174 output stopped (ixon flow control)
176 output stopped (carrier flow control)
178 output stopped (CTS flow control)
180 output stopped (DSR flow control)
184 send SIGIO for input events
194 next character is literal
196 retyping suspended input (PENDIN)
198 counting tab width, ignore FLUSHO
200 block mode input routine in use
207 Kernel address of the session structure.
209 Process group for which this is controlling terminal.
233 Extract values associated with the name list from the specified core
234 instead of the default
237 Extract the name list from the specified system instead of the default
241 .Bl -tag -width /dev/memxxx -compact
245 default source of tables
